so this went from an official reseller list topic to a shoptemp topic??! ooooooookaaaaaay?
Anyways try out this site
www.GamePlayFun.com they have decent prices and are supposedly located in the USA, which should mean quick shipping without waiting times for customs.
Here's a list of sellers who are generally trusted to sell the real deal:
http://www.realhotstuff.com(A bit more expensive than shoptemp, plus no free shipping but a great track record)
http://www.consolesource.com( A tad pricey but very reliable)
http://www.ishopvideogame.com(Good prices, not too sure on reliability as I haven't used them before)
http://www.kickgaming.com(Canadian based company, fast shipping, reliable/as of this posting the SuperCard Series is out of stock and on back order according to the site)
http://www.gamesyeah.com(strikingly similar to ishopvideogame.com's website, in fact so much that I suspect it might be run by the same people)
http://www.5thdimensionstore.com/(Average Pricing, Supposedly fast shipping, possibly free shipping??)
http://www.modchipcentral.com(Don't know much about this one but it seems average in price, maybe someone here can give us more info on them??)
http://www.gamekool.com(Heard only good things about them, no personal experience though, good pricing)
Keep in mind that these sites are mainly for buyers in the US and Canada, though a few of them do ship internationally.
