Global Trade Market...questions...concerns...complants!!!

Well until the update, some of which is great, I didn't have a lot of luck with trade, everything always seemed the same. All light bulbs or all fridges depending on the most recent level up. But now although there is more variety it is pointless even trying for the dozers, wheels or bars and all that spinning and going on just means you lose those vital few secs to get back to the market. As far as I am concerned they really messed the game up for me - gutted and sooooooooo frustrated :-(
