Offer Check

Compare manually entered HKD offers, quantities and qualification. Unknown eligibility stays unresolved. Inputs are temporary.

Compare manually entered HKD offers without hiding the assumptions behind the price. Enter 2–6 offers for the same product and quality. Choose the price meaning explicitly: • Single pack: the final total for one received pack. • Final-total bundle: the total cash for all received packs. • Buy N, get M free: the stated price per paid pack × N; received packs are N + M. See cash paid, quantity received and exact unit price separately. A lower unit price can mean a higher bill or more surplus; the tool does not know how much you need. Qualification starts Unknown. Check actual membership, coupon, minimum-spend and other conditions yourself before choosing Yes. Unknown and No rows remain hypothetical and cannot win the confirmed-only comparisons. At least two Yes offers are needed for a lowest-unit-price or lowest-cash conclusion, and any Unknown offer keeps the comparison incomplete. Ties keep all matching row positions. Choose explicit g/kg, mL/L or whole-item quantities. Six-decimal displays are labelled, while ranking compares exact fractions. The tool does not infer density, other units, exchange rates, repeated promotional groups, leftover pricing, coupon stacking or extra charges. Include the intended final charges yourself; use a final-total bundle for a separately adjusted checkout total. Preview before copying. Changes to input, mode, language or rows require a new preview. Source labels are inert text: no shop or URL is fetched or opened. The invented example loads only when you ask and still requires Preview. Replacing authored data, clearing it or removing an authored row asks first. English and Traditional Chinese. No permissions, website access, account, analytics, payment feature, persistent storage or extension network requests. Entries, eligibility notes, results and language remain in this open workspace only. Copy what you need before closing, reloading or updating. Copy writes the reviewed report deliberately and never reads your clipboard. This is a manual scenario calculator, not a live price monitor, eligibility checker, buying recommendation or savings guarantee. Support: homingmobile@gmail.com.
