I'm a bit confused about something, and realize that I'm probably just overthinking it. Let's say I'm selling a product. I have the paypal account. I have the E-junkie account. I add a new product to E-junkie, upload the file, copy and paste the cart buttons into my sales page. Is there something else I need to do to make sure the buyer actually gets the file after they purchase? Once they purchase, where are they redirected? Does E-junkie automatically mail them the file/download link?
