I like how easy it was for me as an administrator or even just using my account at work we could set up our domain without any problems! They also have great support when you need help with something in their system which they are very quick about getting back too us if needed.
Nothing really bad but maybe more options would be nice? Maybe some other payment methods not only credit cards so people can use this service outside banks where available?? This product helped make sure all payments were encrypted from point A (client)to B(affiliate). It's simple yet effective way of doing business online today!!
