I’ve seen “cash discount” before. once or twice, in the past... say 30 years of shopping.
It wouldn't be hard to offer a cash discount at checkout. But cash purchasers are already subsidizing credit card users. The shelf price already reflects the credit card fees.
Most cash payers don't realize that they're subsidizing credit card users. And it isn't in the merchant's interest to tell them.
That's why I pay by credit card everywhere, and then pay off the bill at the end of the month.
BTW, there may be a minimum fee per transaction, charged to the merchant, which is why "$10 minimum on charges" signs used to be common. I have to pay a $1 minimum with the credit card processor for my on-line business.
It's not included in everything, on a daily basis I have some one try to charge 2 & 3 dollar items.
I am constantly amazed by the amount of adults who do not even have a nickel on them.
I’ve known a few stores that gave discounts for paying with cash. Not many, but a few.
Merchant service contracts prohibit the offering of discounts for using cash, that’s why stores don’t do it.
I think we will see mini mart type business starting to use surcharges on credit purchases under $10 now that they have the right to do so.
