Are my sales protected by SSL?

Absolutely! When you get to the checkout screen, you'll see a lock in the top righthand corner of the overlay. If you click that lock, and follow the prompts, you'll be able to open a window that shows the SSL Certificate. The reason we hide the url that shows "https" during checkout, is the url shows in it, and we don't want your customers to think they're paying us (which they aren't), or on our site. We want them to feel like they're on your site and they're paying you.
