I'm a bit baffled.  I think I missed something, and even after re-reading the manual I don't know where to edit/fix the order-purchase-download procedure/process:

After a successful PayPal purchase, clicking the "Return to site" button brings the purchaser back to the index page of the shop. Isn't it supposed to link to the thank-you page?

The DigiStore issued 3 thank-you emails - the first one with the correct amount, but the next two with zero amounts and additional order numbers. Is this a bug, or do I need to correct something? [The thank-you page is OK, but perhaps I need to tell PayPal where to link after purchase, and if so where?]

Neither the email or the webpage instruct the user where to download the product. Do I need to edit the thank-you email with any additional text or URL? Does EACH product need to have its own particular download-license instruction/confirmation email?

Looks like I'm almost there - your suggestions are most appreciated and I'm very eager to post the shop as an example in your forums!

Thanks, Rob.

I'll be testing this with the client in a day or so, but I think I've got it figured out; I missed the Paypal IPN part - doh! - and think that's the key to my dilemma.
