Expect two payment moments
First you pay Superbuy for the item and Chinese domestic shipping so the agent can buy and warehouse the goods (Stage 1).
Later, after warehouse QC, you pay international shipping — often as a deposit against the live quote — when you submit the parcel (Stage 2).
Spreadsheet shortlisting does not charge either stage. Treating a card price as “already all-in paid” is a planning error.
Before setting your item budget, compare saved CNY prices in the spreadsheet. These snapshot prices are research references, not checkout totals; confirm the seller price and additional costs before paying.
