All of the software payment sites that start with "Reg" are scammers! RegSoft, RegNow, RegNet. All part of Digital River. Another affiliate of DR is ShareIt!, which marks up their conversion rates without mentioning it. And all of the DR "Reg" sites claim that they now accept PayPal payments - but they really don't want you to use it. Three purchases with them (Two w/RegSoft, one with RegNet) where I used PayPal, the payment did not go through - so they claimed - and insisted that I pay again at their site using a credit card. Twice I had to get PayPal to contact them to prove that they were paid by PayPal already.
In each case they told me that this wouldn't be a problem if I paid with a credit card directly to them instead of using PayPal. Then why do they offer it?!?!
