Gas stations do this widely in my area, I wonder what their take rate on debit vs credit is. I've never seen data on that, unfortunately.

Amazon/Target/Walmart etc are in an interesting situation re: who would blink first on implementing surcharges. They haven't yet in 5 years, but of course that doesn't mean they never will. Walmart is the one that would seem most likely in terms of targeting value-first customers, Amazon in terms of technical flexibility (e.g. you can already link your checking account if you want), but a lot of the other ones desire those sorts of more financially-sophisticated customers.

Local gas station said their CC payments were 2.5% while debit card payments were $0.25 per transaction. At one point they had a sign up encouraging debit card use
