I remember when my son got a part-time job at a Radio Shack, he was amazed to see people (mostly older people) walk into a store to buy things that could be had for almost half that price at online outlets like Tom's Hardware, NewEgg, Amazon, etc.
A few years back, I saw the handwriting on the wall for these brick-and-mortar outlets when customers started walking into these stores with iPhones. They'd check out the merchandise in the store, see what they wanted, and then they'd walk out of the store keying in their order on the iPhone.
