What should I check in a seller's quotation before accepting it?
Check for exclusions that would require an additional arrangement. Do not accept an ambiguous scope solely because the total appears attractive.
What should I check when reading a translated product listing?

Which purchase records should I keep for later reference?
Keep later amendments alongside the original confirmation. Retain information explaining any ongoing arrangement when one applies.
