Why is everything so complex with this stuff, lol.
I've got a U2 here and would love to try this on, but I have no interest in dinking around with "amigacoins" or "indiecoins", whatever they are.
If you're selling it, give me a clear and concise link to click where I can see what it offers and if it's to my liking, I can pay with real money via a paypal link.  Not "amigacoins", "indiecoins" or one shiny donkey for payment.  No special client either, dear God.  
I applaud your efforts, but when one has to jump through hoops to obtain what you're offering I do have to mention it.
I'm throwing money at you.  I'd love to try this.  I don't know, and don't care - what an "amigacoin" or an "indiecoin" is.  You show me a link where I can get this, a traditional way I can pay for it without using some special "AppStore" client for some obscure AppStore I've never heard of and will never use again, and I'd love to take a look as this.
K.I.S.S.
