I gave them a try and didn't see big savings. I canceled and was charged a fee for canceling when I had been assured there would be no cancellation fees.

Nothing from the rate quoted to free paper supplies was true. Worst customer service invested hours in phone calls, texts and emails with no resolution. Ended up being charged a $350 cancelation fee and now the leasing company is trying to charge a fee on a promised "free" terminal. Nightmare.

MainStream offers a choice of different universal terminals, which avoids getting locked in. It's also nice to see interchange plus pricing touted as the standard pricing model.
