> The consumer using Visa SuperRewardsPlatinum probably doesn't know that it's costing the retailer more than other cards when they use it. You mean the merchant pays a higher fee when you use one Visa card vs. another Visa card? Or you mean compared to Mastercard etc.?
I seriously doubt the retailer pays different fees depending on th card. That sounds bizarre.
For a large retailer like Kroger, there's no way in hell they're leaving all the interchange discounts on the table.
