What's new in 1.1.133

OfferUp is now a full marketplace in Sell The Flip. You can post local pickup listings, import the items you already have listed, and take them down from Listings or the listing editor.

When you post, we fill the title, photos, price, category, and condition. Import brings in your current listed items (not sold ones). If an item is already archived on OfferUp, we treat it as already down instead of showing an error.

Sold OfferUp items show up on Insights with your other marketplaces. Local pickup sales have no seller fees.

To start, sign in at offerup.com in the same browser as this extension, then open Connections and pick OfferUp when you post or import.

What's new in 1.1.132

Vinted posting no longer fails on categories that already offer Small, Medium, or Large. We were sending extra item measurements those listings do not need, and Vinted turned the post down. Update the extension, then try that listing again.

What's new in 1.1.131

• Vinted import still works if you have been logged in on vinted.com for a while. Open Connections or Import and pull your closet as usual.
• Mercari now accepts titles and descriptions that include emoji or decorative symbols. Those characters are removed so the listing can still go up.
• Poshmark sync finds listings that used to be skipped on a small refresh. Sync All and a single-closet sync still do not post or change anything on Poshmark.
• If a Poshmark item is already sold, delist now finishes cleanly in Sell The Flip instead of looking like a failure.
• If Whatnot rejects a photo, the message now says it is their community guidelines check. Try the same photos on whatnot.com if you need to confirm.
• Scheduled Facebook posts keep your Hide from friends setting. The default stays hidden unless you turned that off in Listing defaults.

What's new in 1.1.130

Facebook Marketplace posts that were failing with "Your Request Couldn't Be Processed" should go through again. Sign in to facebook.com in the same browser, then post one listing to Facebook from Sell The Flip.

What's new in 1.1.129

Whatnot posts that need a backup category now use a working Other category instead of one Whatnot no longer has. That stops the same Whatnot error from repeating and then blocking the post.

Posting, import, and fill on the other marketplaces work the same as the previous store version.

What's new in 1.1.124

• Depop: posting a new listing no longer sits on "Creating listing" with no error. Keep depop.com open and signed in in the same browser, then post one listing from Sell The Flip.

• Facebook: syncing several listings at once now finishes instead of dying mid-run on Facebook. Select the rows on Listings, hit Sync, and each Facebook listing is read on its own.

• Poshmark: importing a closet now brings the SKU / closet code into Sell The Flip with the listing.

What's new in 1.1.121

Facebook Marketplace posting is more reliable. We now pick up your Marketplace location from facebook.com, so new listings are less likely to fail with a blank "Your Request Couldn't Be Processed" message.

If Facebook still refuses a post, we tell you to try the same item by hand at facebook.com/marketplace/create/item first. We only mention switching off a Page or professional profile when that is actually the issue.

Sync with Facebook should no longer sit silent until the site says the extension did not respond. You will see progress while we connect and read your listings, and a clearer message if Facebook stops mid-sync.

Stay signed in to facebook.com in the same browser (personal profile) when you post or sync.

What's new in 1.1.120

• Whatnot posts that failed because Chrome withheld site access now have a clear fix: use “Grant site access now” on the posting screen, or open the Sell The Flip toolbar icon and grant marketplace access.
• Vinted import is more reliable when you are already signed in at vinted.com. Open Import, choose Vinted, and your closet should load instead of getting stuck on a sign-in error.
• Photo uploads are more reliable on Mercari, Depop, Facebook Marketplace, Grailed, and Whatnot, including photos already saved in Sell The Flip.

What's new in 1.1.119

• Vinted books: a 10-digit ISBN from an older book is accepted, not only the 13-digit barcode number. Put it in the listing's SKU field.

• Depop: a shop that has sold items before no longer gets stuck even if nothing is for sale right now. If you have never listed on Depop, we tell you to finish Depop's first-time Sell setup (including Payments) before posting.

• Clearer errors when a post or delist fails. You see a short message instead of a wall of page text. Poshmark already-sold delists and mixed eBay photo problems are called out in plain words.

What's new in 1.1.118

Posting and delist errors now show a short, readable sentence. You should no longer see a wall of code, HTML, or JSON when something fails.

If your Depop shop is not set up yet, posting to Depop stops right away and tells you to finish setup on Depop, instead of sitting there with no answer.

If you delist a Poshmark item that already sold there, we just clear it in Sell The Flip. You will not get a "may not delete a listing that has been sold" error.

If Facebook needs you to sign in again, we say that plainly so you can open facebook.com and retry.

What's new in 1.1.117

Opening a listing that is already live on Vinted no longer pops extra Vinted windows just to load sizes and category fields. The sizes you already picked stay on the form. Click the Vinted size field, or change the category, when you need a fresh list from Vinted.

What's new in 1.1.116

Listings you import from Vinted can now post to your other stores with their photos. After you imported from Vinted, posting that same item to Poshmark, Mercari, Depop, or Whatnot could fail on every photo and ask you to reload the extension. The photos on the listing were fine. This update lets those photos upload.

Update the extension, refresh selltheflip.com, then post one Vinted-imported listing to try it.

What's new in 1.1.115

The toolbar popup no longer asks you to sign in to Sell The Flip. It now lists Poshmark, Mercari, Depop, Facebook, Whatnot, Grailed, and Vinted, and shows whether you are signed in on each site in this browser. Click a row to open that site. eBay still connects in Sell The Flip (use the note in the popup to open Connections).

Facebook imports skip listings that already sold, so they do not come into Sell The Flip as active inventory.

If Mercari needs you to sign in, you get a clear sign-in message instead of a confusing error.

When you run Sync, a sale on a marketplace can show up right away instead of waiting.

What's new in 1.1.113

Facebook import skips listings that are already sold, so they no longer show up as live inventory in Sell The Flip.

If Mercari blocks a photo upload (usually because you are not signed in, or a popup was blocked), you now get a clear “log in and try again” message instead of a wall of error text.

What's new in 1.1.113

Vinted is no longer included in Sync or automatic sold-item flags. Vinted treats those automated checks like automated posts, so we leave them off on purpose.

Importing your Vinted closet and taking a Vinted listing down from Sell The Flip still work the same way. When something sells on Vinted, mark it sold on the listing yourself.

Sales Insights no longer pulls Vinted orders. eBay, Poshmark, Mercari, Depop, Grailed, and Facebook sold flags are unchanged.

What's new in 1.1.112

Safer posting to Vinted
We now leave 5 minutes between Vinted posts (and still cap new ones at 10 a day) so your closet stays in good standing. If you try to post again too soon, we tell you how long to wait, or put it in your Listing Scheduler.

If Vinted pauses listing on your account
We stop sending new Vinted posts and edits until that pause lifts, normally about 24 hours, including taking sold items down. Your other marketplaces keep going.

More Vinted details filled in
Categories that ask for extra answers (for example computers: brand, condition, storage, RAM, charger) now get those fields from your listing, so Vinted is less likely to refuse the post.

To post to Vinted, sign in at vinted.com in the same browser as this add-on, then choose Vinted when you post from selltheflip.com.

What's new in 1.1.110

Vinted books post correctly
Book listings on Vinted now include the ISBN and the language the book is written in, both of which Vinted requires. Put the ISBN in the listing's SKU field (or anywhere in the title or description). A Book language dropdown appears when Vinted and a Books category are selected; it defaults to English.

Vinted posting stays careful
We still space Vinted posts 2 minutes apart and cap them at 10 per day, so your closet stays in good standing. If you try to post again too soon, we tell you how long to wait.

To post to Vinted, sign in at vinted.com in the same Firefox profile as this add-on, then choose Vinted when you post from selltheflip.com.

Vinted posting is live
You can now post listings to Vinted from Sell The Flip, the same way you already import and delist. Category, condition, brand, color, package size, and size are mapped for you, including a size picker that uses Vinted's own options.

What's new in 1.1.107

Vinted
• Import now runs through a real Vinted tab, so login and catalog reads are more reliable.
• You can delist Vinted posts from Sell The Flip. Vinted has no "ended" state, so this deletes the listing on Vinted.

Sale detection
• Sales are checked when you open the app, not only on a 30-minute timer.
• "Sale detected" reminders stay up until you dismiss them or mark the item sold.
• Vinted and Facebook sales are included, alongside Poshmark, Mercari, Depop, and Grailed.

Depop
• If Depop has no matching brand, we set Brand to Other so the listing still posts.
• Depop is allowed for most categories. Only items Depop prohibits are blocked.

Poshmark Sharer
• Share, Follow, and Offers can run together. Writes take turns so Poshmark is not hit twice as hard.

What's new in 1.1.107

• Mercari: posting is more reliable for accounts that are already verified. The listing request now matches Mercari’s own website, which should stop some false “verification required” blocks.

• Depop: unknown brands now default to Other so the listing still posts. Package size is chosen from the weight you enter in Sell The Flip (including Large at 2 lb).

• Poshmark Sharer: Share, Follow, and Offers can stay ready at the same time instead of locking each other out for the day.

• Sold items: when you open Sell The Flip, we check your marketplaces for new sales sooner.

Version 1.1.105

Depop: listings that are not clothing (for example phone cases) now send Brand as Other when we cannot match a catalog brand, and we no longer invent a Men/Women department for those items. Quantity stays 1 unless you set another amount.

Poshmark Sharer: Follow now skips closets you already follow, so a follow run actually adds new people.

Version 1.1.104

When we detect that an item sold on a marketplace, we no longer mark it Sold for you. You get a reminder with the item photo and title so you can mark it sold and take the other posts down yourself.

No changes to posting, import, or other marketplaces in this version.

More reliable Whatnot posts when a category needs extra details we cannot fill.

• Listings that Whatnot rejected for a missing product type (for example coins) now retry under a more general category instead of failing
• The same retry applies if you later edit a live Whatnot listing into a category that requires catalog or product-type data
