I'm stopping all play until the trade system functions rather than frustrates. I just wasted over an hour trying to get one of four items, only two if which should be considered rare. I clicked over a hundred times, and only twice were the items still on the shelf once the city FINALLY opened after the usual lag delay. Both time llamas got scapegoated as the items wasn't actually available.
I'll check back in a week or two to see if EA gets their act together and provides a functioning trade system. If not, DELETE!
