Replacing Merchants' Inventory
If you do not find something that you want from a merchant, then this cheat will give them a completely new inventory. First, after you have decided you do not like a merchant's inventory, save your game, unless you have a recent autosave in the same place that the merchant is in. Next, attack the merchant. It is not necessary to kill it. Then, reload to your last save. Finally, look at the merchants new inventory to see if they have what you want. Repeat this process if they do not. Note that specialized merchants will still only have items in their specialized field. For example, alchemists will not suddenly carry Daedric weapons, but will still carry mainly potions and ingredients.
