Yes, it's an American thing. In the US every retail entity that you interact with will offer you discounts to scan a plastic card in addition to your credit card (it allows them to trend you as a consistent customer for their data modeling, send you targeted advertising, and so on).

If you want to take advantage of these discounts, you build a significant stack of plastic.

As a question, what kind of percentage discount are you getting for this data exchange?

I'd guess on the order of 10%.

At a grocery store, selected items are discounted (usually to half off). At a restaurant, you might get every tenth meal free.
