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

Awesome game soured by a poorly implemented, or at the very least untested global trade market.

Click. Wait. Not listed.

or

Click. Wait. Buy. No longer available.

or

Click. wait. Buy item. Item not available but coins deducted !

And if these items are flying off the shelves so fat, how come my own seem not to? 

Entirely frustrating and a waste of game time.

And implement a search please. I am buying specific items. I am not going to randomly buy any donuts.

Thank you

Tim
