I have been playing for about 15.5 hrs now and have found that after I get through a dungeon I can no longer sell the item I have collected.

It seems to be the lower items like Fur, Iron and alot of steel items even if they are enchanted!

Just wondering if this is happening for a reason.

Thanks for any help.

Can you be more specific? From my experience, certain merchants do not buy certain item types.
It might be a number of things causing this though.

Ok sorry.

Any dungeon I have been through I usually go back to the same trader, in this case the blacksmith in Whiterun.
Every time I have just unloaded all my stock to them ie. Weapons and armour eg. Iron, Steel, Leather, Furs and so on.
Now all of a sudden I am unable to sell these items to them (Iron, Fur, Steel and so on. The lower grade items). I can only now sell Silver, Orcish or better items (couldn't even sell a dwarven shield to them)
Pretty much this is the only thing bugging me in this game so far but I dont know if they have added this in to limit profit or if something is wrong.

Thanks again.
