Debit card swipe fees

I'm so glad our government stepped in to save us from the evil banks charging merchants too much for debit card swipes!! Yeah, I know the banks are introducing fees for debit cards, but the prices in the stores are going DOWN since they don't have to pay the evil banks so much, so all is good, right???

But, the banks can't charge fees for debit card use.... there otta be a law!!!
