Ask HN:What e-commerce package should I use?
tstegart: I would look into Amazon Webstore as well, just to see if it meets your needs. It is less customizable in terms of changing the code, but it definitely encourages purchases, which Amazon has down pretty good, and you can also probably get a few products that you might not want to stock, and sell them on commission. You can always build the social part over the store, with people only going there to purchase something.
