That is legit - and that is where Wal Mart gets their tanks (That's what you'd get at Wal Mart.)
A 50 gallon tank is NOT $300, UNLESS if it comes with all the bells and whistles, and stand, canopy, etc.
A 75 at PetsMart is $160-$165, and you add on from there. (I should know. I've bought 3 brand new ones that way.)
In fact, if you want a cheaply built tank, you can even get a 75 "E" which has thinner glass, for about $100. (New.) But I would not recommend it.
