Well, like I said in an earlier response. What the GB host requires you pay in paypal fees is really up to them, as the international rate for USA is around 4% + .30. I can't speak for or guess at what people that don't have USA accounts pay.
However, the calculation should be item cost + gb fee + paypal fee on top of that. Not having the HDN on top of the paypal fee.
The intent for paying the paypal fee has always been to cover the cost of sending the seller as goods. If we were all a professional store front, we could accept credit cards, but then we might be doing this professionally and not on our days off and in our free time. lol
That is a requirement of the retailer, in order to secure the copies. You'll note that NovaMedia only publishes their listing a short time before the items are released.
I wouldn't lay the blame at the feet of the people that are getting the copies for you - if you are really mad, go after the retailer and ask them to change their business practices.
Yes, that has been a requirement of HDN, we are not asking everyone to switch over ongoing group buys to the new system, only items that are newly listed.
