Another way is:
All items in the market should be buyed & selled by the system (maybe heinz stadt and so on), and all players can buy stuff from the system. With this way are all items available, as long someon selled it to the system.
An optional way for unavailable items is a preorder system.
The current system sucks... it is very slow for the most countries... it is buggy and shut down the game - and you need to restart your whole tablet after a few times. (Asus memo hd pad 7)
But the baddest thing of the current system are the unavailable items...It takes very long to find an object, and then it is no longer available, because the system sucks. Each 30-40 "shopping tour" is a success... the rest is not available. It's nice to sell items but it's bad to buy something.
