I've been searching for these types of sites for the past week or so. Unfortunately, there aren't very many like that anymore, and a large chunck of the ones that are require good credit. And the ones that don't are just in general very very difficult to find.
LTD and ABC are nothing new, as they've already been talked about in this thread a number of times. However, I didn't see BMG rise in discussion. I'm sure most of you have heard of it...When you sign up, you get 7 free CD's to start, they send you your order which generally takes 2-3 weeks, then after you pay them for shipping and handling, you are free to order from their site. They have a plethora of things, not just music. In fact, I'm doing a large chunk of my Christmas shopping from there this year. I've done business with them for years, and in my experience they've been great. I'd highly recommend it to anyone, especially during the Christmas season when it can be hard to stretch your money.
Edit: Found another site, this one is for magazine subscriptions. They have some great prices! They also offer the option to buy them for a gift! Check them out!
