My great idea

You know what 7-Eleven should do? They should team up with a local supermarket and let customers order groceries and stuff online or directly from a catalogue in the store itself. Customers would then pick up their things at the 7-Eleven nearest their house the following day. This would not be for families to do all their weekly shopping. It would be for people who need an occasional bag full of groceries and other things that aren't currently available at the 7-Eleven but don't have the time to make a special trip to a large supermarket. It would be a great time-saver and, as we all know, in Taiwan life is all about convenience. So is this a great idea or what?
