Canonical Stuffer Shack would imply that things aren't all matrix commerce.
I'm not saying exclusively so, and indeed, this wouldn't apply to all form of retailing. Food is not going to be mostly matrix (though it certainly will have a portion: you can probably get a drone to deliver you a burrito at a moments notice) and things like convenience stores aren't going to go away.
There are a lot of considerations at play when considering the future of shopping. It's not all about efficiency. While something CAN exist, such as the idea of omnipresent matrix shopping, as humans it's going to be hard to shake off the social aspect of going to a store.
I suspect that wageslaves will have a certain behaviour pattern, and non-corpses will have another. Wageslaves, working 100 hour week standard, are going to want to be pretty efficient in their shopping and matrix order everything. Hell, they probably all subscribe to recurring service stores, the kind that simply deliver you new clothes picked out just for you every month. They don't go shopping. It's all delivered for them. Their whole lives are managed for them. They call it efficiency and sneer at the non-corpses and their primitive ways, while non-corpses shake their heads sadly at the wageslaves that no longer experience any pleasure of freedom, such as going to a store and walking around and picking out clothes and making bad, good and best choices.
