About this extension
A small receipt-style counter for the costs that a headline price leaves out.
Enter two offers manually. For each, specify the price per paid pack, paid-pack count, quantity per pack and unit. Add delivery or other fees, a percentage discount and an optional discount cap. A buy-two-paid-packs-get-one-free option adds a same-size bonus pack for every pair of paid packs.
The two receipts show paid packs, free packs, merchandise subtotal, discount, delivery and cash total. Unit price includes delivery and uses the actual received quantity. Compare mass in grams/kilograms, volume in millilitres/litres or individual items. Different unit families are not ranked against each other; the counter never assumes that a litre weighs a kilogram.
Enter how much you need to see which offer leaves you short or supplies extra. The lower unit price and the lower cash payment are treated separately. If free delivery is available above a threshold, the counter checks up to 100 paid packs and reports the first qualifying quantity, its total cost, extra cash required and received quantity. It does not automatically add extra packs or imply that free delivery is the cheapest choice.
Calculation rules are visible: prices use two-decimal money amounts; discount percentages accept up to two decimal places; the percentage discount is rounded to the nearest cent and applied before delivery; a zero discount cap means uncapped; a zero delivery threshold disables free delivery. Displayed unit prices are rounded to cents; ties at that precision are labelled accordingly. The threshold is checked against the discounted merchandise total. Include applicable taxes in the prices you enter. Check the seller's actual terms, particularly whether promotions can be combined.
This is a local arithmetic tool, not a shopping scraper or a checkout guarantee. It does not retrieve prices, apply coupons, purchase products, convert currencies, estimate density or make financial recommendations. Both offers share your chosen currency label.
