I've used trialpay on occasion since 2007. In the early years, they fulfilled their promises and delivered the software flawlessly upon completion of the offers. Recently I put in an order for book collector software "collectorz.com" and when I did not receive my order I contacted trialpay.
The responded that I was using two different accounts (complete bull) and that I was not eligible to receive the product.
I think they are losing money and ripping off their customers. Stay away, far away. I think we should just pay for the software directly to the good companies that create it.
