> Why not just sell discounted "non-returnable" versions of products, the same as you can buy discounted non-refundable airline tickets? Online retailers often do just that. You may see a retailer have a section called "final sale" or "last call" for discounted, non-returnable merchandise. Others simply offload the merchandise onto EBay. I have bought things that way, but often I have regretted it. In general it is hard to evaluate online goods before purchase, and if something ends up on "final sale" it probably wasn't selling well to begin with for a good reason.
