Remove the barter refresh cooldown or reduce it to 2 hrs. The only purpose of the cooldown there is to annoy ppl, and the change should be a realy quick one if it is a reduction, just change the time from 4 hrs to 1/2hrs or something like that. should be just reassignment of a variable.
For once, it's the people paying for VP that are annoyed with this :D
