I agree with Taosaur: It's not at all difficult to make your own card and save a couple of $$, and, maybe more important, time. (You can make it NOW, just go get an empty card and go!)
I made one (well, two actually, gave one away...) and if I can do it anyone can! I had very little knowledge about these things, just followed instructions!
Just saying...
Having said that, I think the ready-made N2A seem well worth their price as well.
