Yesterday this was working fine.. sell and item in your inventory to a merchant that already has the item a few times and it will appear in your inventory at 100% condition.. not working today.. hmm?

I have mixed results trying this. I have tried the 9mm pistol everywhere, and twice I have gotten it to work. Thing is after selling and rebuying it 6-7 times it disappears! I sell it back and then it's not available to rebuy. I did manage to make a few hundred caps but those were quickly spent when I hit freeside.
