Hi Dan, Since the whole cart sits in a user var array, after a successful purchase I dump the cart into a new user var array called something like last purchase and create another user var called last purchase ts. If that user tries to process another transaction within 15 minutes, I compare the carts and if they are identical, I shift them to an error cart duplication page and let them know that if this is not an error, come back in 15.
It's not the perfect solutions and I'm sure that someone else may have a better one.
