How cheap do you think flat irons are at A. J. Wright's?

That is hard to say, it depends on the brand and how they got them, (such as overstocks, returns)  You could also try one out, if it wouldn't work, you could always return it for a refund!  If you are still to wary, I suggest just buying from a more reputable, well known store!  Sally Beauty Supply has a Heatmaster Professionals flat iron selling for $29.99
