Hmmmmm, I've noticed no difference in prices between my debt and credit card purchases. If I buy a bottle of water at the gas station with my debit card, it is $1.59. If I buy it with my Amex Gold card, it is $1.59. This is just one example, but I could give you hundreds. If you are paying higher prices for goods just because you use a credit card, you should look into paying in cash. But, then you wouldn't get any purchase protection beyond the standard return policy, and you wouldn't get an extended warranty unless you pay for one separately. I'm not saying some places don't charge more for credit card transaction fees, but I've never seen it happen enough to where I would want to ditch my Amex card. It rarely happens in my use case.
