Yes, NDN does have it right to give gifts of Amazon cards to winners of their PokerStars home games.
I really thought many forums would go this route, but being honest, there are maybe 5 viable poker forums remaining(but what do I know). Paypal gifts, JWAT77, are also a wonderful idea.

I was able to give a donation to a forum for having a freeroll on Americas CardRoom using P2P transfer in the ACR Lobby. It was pretty nice of the small forum stepping forward to offer a freeroll and they said it would be nice to receive donations. So I made a donation before the tourney and I ended up winning first place at another one of my unrelated tourneys.

Carbon.ag and Sportsbook.ag taking long to give payouts to their players(6 weeks +), which reminds the current batch of remaining players if it is even worth continuing to play if their bankroll could become play money.
