Well, not to air too much dirty laundry, but SPS took advantage of us from the get go, and that is why we first developed an integration with Mercury. SPS said your rates will be 2.8%, for example. After three months of our rates never being under 3.1%, we found a payment processor that actually delivered the rate they promised. And to think, we were supposed to be ""partners"" with SPS. Ugh!
