They've had it around here for a while now. Its great for when you go in and buy something that doesn't require a behind the counter part, as you no longer have to wait in line for the 1 person that is actually in the store trying to take care of everyone. Scan the item, pay, and leave. SCO can be great when done properly, it isn't for checking out a cart full of groceries, its for a few items only. Problem is that most stores, like Walmart, tried to make it into how to pay for everything and that is not what is it for.
