In Vancouver, we have Videomatica, which transitioned from a big rental facility with a good specialty retail section to a retail-only store. I shop and special-order from them, and their prices are competitive with online prices. We also have a few HMV locations in the area, with a new downtown...
There were mailmen before Amazon, but I see what you mean. Some of my friends are, or have been, posties, and deliveries of online purchases are a big part of that business. Absolutely no offence meant to Postal Service workers.
I certainly do buy online if I must, and I'm glad I have that option. I just support bricks-and-mortar whenever I can, though my options have shrunk down to a handful. I wonder about shopping in the future, when nobody remembers retail outlets. What will "shopping" even mean then?
I like stores. I don't like online shopping. I like handing money to an employed human being. I don't like my credit card payment going straight to Jeff Bezos for something that gets brought by the mailman, who already has a job. I like walking into a retail environment full of wonderful things...
