Delivery is electronic.

• For some products, delivery will be a license key or activation code. And that's automated by the shopping cart. The shopping cart will send you multiple e-mails; check each one.
• For other products, it's going to be the actual product.

In nearly all cases, if there's a trial version then what you are buying is the license to unlock it to the full version. If there's no trial version, the developer will send you instructions and files within a reasonable time.
