Don't use this service. Their customer service is awful. You can't even get someone on the phone.
They are very deceptive when it comes to their transaction limits. They fail to disclose, right at the beginning, that they have a daily and per transaction limit. They put me in a very bad position with my customers because they failed to calculate how many transactions and how much in transactions i would be processing. Their inability to anticipate their customers needs makes them look like a bunch of amateurs. Try using Fatt Merchant instead out of Orlando, Fl. Much better company!
