Oopbuy coupon checker and points clock
Two small tools that apply Oopbuy's published rules to your own numbers. They tell you which bill a reward lands on, whether a minimum is met, whether a window is open, and when points expire.
How to use the code reader
Pick a reward from the list. Every option comes from the public coupon list or the event calendar as read on 15 October 2026. Enter your product bill and your parcel bill in yuan; only the one that matches the reward's tray is used. Pick the date you plan to pay. The tool checks dates in a saved record, not live account eligibility; opening and closing days need the exact time checked in your account.
The result shows the tray, the shape, the minimum and whether your bill reaches it, the published amount or rate, whether the window is open on that date, and the source. Stacking always reads not stated, because no official page says otherwise.
How to use the points clock
Enter an amount and the fee type, then two dates: when you pay, and when the parcel is expected to leave the warehouse. The clock applies the base rule (one point per yuan, rounded up), checks whether the payment date is a Tuesday and whether the fee type is on the Tuesday list, and works out the expiry from the dispatch date.
Use the dispatch date honestly. If an item will sit in storage until December, its points will be issued in December and expire on 31 December.
What the tools will not tell you
Neither tool estimates a saving. A percentage coupon with no published ceiling cannot be turned into a yuan amount without inventing a rule, and the total you finally pay depends on the line, the parcel's weight and size, and the currency your account displays. The tools also never mark one coupon as better than another.
They do not connect to your account or send anything anywhere; the arithmetic runs in this page. If the operator changes a rule, the tools will be wrong until our next reading, which is why each result names its source and the reading date sits at the top of the dated codes page.
A worked example
Say you have ¥320 of items in the warehouse and an estimated parcel bill of ¥640, and your account holds the ¥699-105 shipping ticket. The code reader will show the parcel bill as the tray, report that ¥640 is ¥59 short of ¥699, and show that the window runs to 31 December.
Your choices are then concrete: ship without that ticket, use another eligible ticket, or combine a genuinely planned item after comparing the extra freight and item cost. Do not buy unwanted goods solely to cross the threshold. Whether a different ticket in your account works better depends on rules the operator has not published, such as caps and stacking, so we leave that decision to the checkout screen, which shows what it will actually accept.
