I agree with Carg.
The only things I ever bought from the shops were my initial suits of armor until I found better ones along the way.
You will end up finding more potions than you will ever use.
Sorry the game has to be difficult for you but I am glad you can and are playing anyway.

I haven't seen this exact problem, but I have noticed that the mage shops sell almost the same things the armory sells, and usually a few additional items, too. And usually, the temple has the best potions, if you really need to buy some. But I think Moni and Carg are right, you can get more and better stuff while adventuring. If all else in the game seems to be OK, I wouldn't worry about this. By the way, I assume you're installed the patch, right?

Yeah, it does it even after I install the patch
