I just ordered a product using Google Checkout, but I did not receive the download immediately?
When you purchase through Google Checkout, Google may sometimes send you a confirmation email. Before this email is confirmed no money is transferred and so the order is not yet complete. You need to confirm the purchase to Google Checkout using the conformation email you receive, before the order can be processed. Upon completion, you will immediately receive the product. This system is set up by Google Checkout to protect the customers when buying online. Depending on which country you order from, sometimes you may have to simply wait up to a couple of hours before Google completes its checks and the order is successfully processed.
