Customers always wanted low prices- imports became popular because members of the US military had brought various items and equipment back during/after Korea, having bought these at the PX and during leave in Japan. In the '50s, people wanted and bought imported transistor radios, but they couldn't be called 'pocket radio' until the clothing industry made shirt pockets larger. Then, when Japanese cars became available, the American Big Three ignored advice to become more efficient and to make better products, so Toyota, Honda, etc kicked our car making ass because of the arrogance. Easy, cheap/free shipping only adds to the draw.
The part I don't understand- many items need to be touched, felt, used in demonstration for the potential user to really find out if it's suitable but living in a remote location makes this an attractive way to buy, just like Sears and Montgomery Wards catalog sales. I get it, but I don't like a giant corporation to kill off small dealers. The personal service from local stores definitely can make life easier, if they would only understand why they exist and that if they continue to hire people who don't have a clue, they'll become one of the "I wonder what happened to the '___________' store?" statistics.
