In article ,
they tried to charge us 5% for each transaction. (The other cards -- Visa,
Mastercard & Discover -- charge us "only" 4% for the privilege of "working"
with them.)

Given this, why don't people like yourself offer discounts for cash any
longer? Seems like less use of credit cards would be to your advantage.

Probably a violation of their agreement with the credit card company if
they did.

Can't speak for Jay but that's a common clause. I've dealth with two
small busniess that gave cash discounts, and they got letters from Visa
(have no idea how anyone found out) saying they had to stop that. Visa
also has rules about what kind of fees you can charge too, my University
is in voliation of that agreement and last time I checked 2 students were
suing the University over it
