Well I'm going to find out, just stuck in an order for two board games of amazon. Over $100 dollars worth of stuff so hopefully its all good.
as long as you pay the invoice and its says ordered everything should be completely fine! like everyone said, talk to the amazing live chat reps if you have any issues or questions!
EDIT: btw i ordered a $350 camera had an issue with the ebay seller listing it as working when it was broken (ebays fault not snapcards), returned it through snapcard got my money back and bought a $400 camera instead and it was all perfectly smooth!
