What should I recheck when returning to an old shopping cart?

Check order records if you are unsure about an earlier attempt. Check that the cart belongs to the account you intend to use.

What should I clarify when I need a purchase by a particular date?

Check whether an action from you must be completed before the process begins. Consider a suitable alternative if the seller cannot confirm enough information.
