Start a worksheet with a status column
For each candidate, record the amount, currency, date and status: reference, quoted or paid. The USD amount on a product card belongs in the reference column. It comes from an imported yuan price converted at the dated rate shown on this site. It is useful for initial sorting, but does not lock the amount you will pay.
Replace assumptions with the selected-option quote
Open the purchasing page and select the intended option and quantity before recording its current amount. Keep that figure separate from the directory reference so you can see which information changed. If the source has no usable price here, leave the amount unknown; a dash is not a zero-cost item.
Keep unknown costs visible
Use separate rows for the items and for any delivery, service or payment costs shown by the provider. Mark unavailable amounts “not yet quoted” instead of entering zero. Add quoted amounts only when their currency and scope match. If one total already includes a component, note that inclusion so you do not count it again.
Use the budget filter for the right decision
The under-$25 view screens the reference item amount only. It cannot establish whether a complete order fits a $25 budget. Before payment, compare the provider’s current total with your worksheet and resolve any missing component. This site does not calculate live shipping or a personalised final bill, so keep the worksheet provisional until those amounts are supplied.
