The selected baseline
One 3.79 USD pump,one 7.49 USD refill and one 10.99 USD cream jar total 22.27 USD merchandise. The baseline combines selected public quotes from different channels,not a live single-store order. Editable prices should be replaced by actual quotes before relying on the result for a transaction.
Full credit and excess credit
A confirmed merchandise-only 22.27 USD credit leaves zero net merchandise. A 22.28 USD credit exceeds that base and is rejected. With separately confirmed shipping 4.99 USD,tax 1.25 USD and other charges zero,the full-credit total remains 6.24 USD. Blank charges are unknown rather than assumed zero.
Exact decimal boundaries
The parser converts values into integer cents. Three units at 0.10 USD total 0.30 USD,and two at 47.99 USD total 95.98 USD;an exact credit equal to either amount is accepted. Negative values,exponent notation,more than two decimals and entries beyond the stated limits are rejected rather than silently rounded into validity.
Promotion rules are not invented
Only enter an actual confirmed credit. The calculator does not determine subscription eligibility,coupon combinations,store rewards,tax rules or shipping entitlement. Each price/charge is bounded at 1,000,000 USD and each quantity at 1,000,000 whole containers. Independent commerce and content review remain pending.
A specific purchase check
Editing a selected price changes the merchandise subtotal immediately. A credit equal to an earlier subtotal may then exceed the new base. The tool validates against the current integer-cent amount and keeps actual shipping/tax fields separate. It does not remember a promotion as permanently eligible or apply the credit to other charges without explicit transaction evidence.
