You are paying your dealer for the amount of hash you receive. If you scale it out and it reads within reason of an ounce, you got a fair deal.

Now the quality of the product is entirely up to you. Nobody is pointing a gun and telling you to buy this stuff (I hope). Inspect it thoroughly when you buy it and make sure you are receiving what you want to receive for the money. Now if you go home and think it's "cut", maybe you should've thought of that before you forked over your hard earned money.
