LOCKPICKS!!!

Thieves Guild smugglers should have about 100 lockpicks on them so you could check them out, or you could go see Shady Sam on the outside of the Imperial City.

Here is a glitch on how to duplicate items(doesn't work on all items and might not work at all, but try it anyway!)

1)Get a bow, the item you want to duplicate, and about 50 arrows(don't use to many or the screen will freeze)
2)Get the arrow ready to fire but don't let it go yet(point it at the ground so it doesn't hit anyone or get lost)
3)Go into your inventory with the arrow still nocked to your bow and drop the item you want to duplicate
4)If you used 50 arrows, then 50 of that item will fall out of the arrow
5)You can now let the arrow go and pick up the items and arrow

Hope this helps!

That glitch won't work if you've donloaded the Shivering Isles pack.

Yeah, because when I downloaded Knights Of The Nine and The Shivering Isles, I couldn't do the glitch after that.

True that I couldnt either
