How much are Nintendo ds wi fi?

To get Nintendo DS wifi you need to either have a wireless internet connection,have the Nintendo DS WiFi USB thingy attached to a PC with internet acesss, or be at a Wifi hotspot. So really, it all depends on how much the place sponsoring the hotspot requires, or how much your internet costs. So in a way, its free, but not totally. I hope i wasn't too confusing @_@ !
