Chris, you have some nice ideas. I like the idea of paying two stamps for a dvd. The whole concept sounds great. I think as your service grows you'll probably be overwealmed by opening, testing and resending dvds. Thats very labor intensive. You may alleviate some of this by having senior members. These can be members who have earned your trust via a number of criteria you establish. You may give people the choice of using a senior member to get the dvd to them a couple days sooner or if its more important to them to go through the two stamp method.

By handling the dvds you double the ones lost in the mail (one change of being lost from the shipper to you, another chance from you to the buyer). By establishing a membership category of senior traders, you cut that in half again.
