If they get into selling other people's stuff in person, they then have to compete with other people in the area on those prices, deal with support for those devices when they break. They also have to deal with all the attendant supply chain issues, etc.
Supply chain for a warehouse is different than supply chain for the store. If too many people in alabama want something tomorrow that isn't in alabama warehouse, they overnight it from vegas and pay the price. If too many people show up to buy something in the store in alabama, they are simply out of stock. In one case, they make a sale and pay a little more overhead. In the other case, they probably don't make the sale.
Additionally, right now their support is limited to "we click buttons, you repack stuff, and we ask UPS to take stuff back to us". The average brick and mortar store provides a lot more support than that.
They already deal with a lot of this for kindle products, but not other peoples.
For other people's products, I can't see them wanting to get into this business, it's a rathole, and only serves to help others more than them :)
I don't think they will get into the business of selling tvs in a big box, for example, right up until best buy dies.
I think they are perfectly happy with "people try stuff, then buy it on amazon", and i don't see why they wouldn't be.
In short, i have trouble seeing why they would want to be a big box in the future. Their entire business model is based around the idea that being a big box is inefficient.
