Its the Same Stuff 作者： Its the Same Stuff

Detailed description:

Every other price tracker makes you bet on one listing. You paste in a
single URL and watch a single ASIN — but the byte-for-byte identical
product, sold under a different brand sticker or in a different pack
size, can drop 30% while the one you picked never moves.

Its the Same Stuff pools the listings you consider equivalent — you decide
what counts, no algorithm guesses — and tracks them as one thing. Set a
single target price (or price per unit, so a 6-pack and a 2-pack of the
same item compare fairly), and get exactly one alert the first time any
listing in the pool crosses it.

• Compare by total price or price per unit
• Automatic background checks, twice a day, whether or not the tab is open
• One alert per pool, held until you clear it — no repeat pings while a
price hovers near the target
• Works fully offline with no account — sign in only if you want pools to
follow you across devices
• Optional sync is self-hosted and passwordless: an emailed one-time code,
never a password to leak
