You never get anything from them after an order (except a receipt). After you get to the confirmation page (step 6 - the one after you enter the next email address in the chain), then just click on "my books" on the menu at the left. Or use Back in the browser to go back to the book/bundle page and refresh - you'll have download links after you purchase.
The emails go out almost immediately, to both the sender and the receiver - - check your spam filters and if you don't find it, just PM the person that was ahead of you in the chain. They can cut/paste the code back to you in a PM here.
