When you take a roommate, aren't you sharing the cost of rent? Sharing can mean mutual contribution as much as it means mutual partaking. Also, what? Amazon is not a retailer? They have giant warehouses, they ship physical product with Amazon logos on the boxes, and they accept returns. They allow for 3rd party vendors, but they are still very much their own retailer. eBay perhaps, but not Amazon.
