I think you are a little confused. Prices on the markets aren't fixed. I always up my prices to the max and they can be chaged from insanely high to insanely low. Now the tapping on an item to find it already sold is a problem. What we need is a one click buy method. When we click on the item in the global hq it needs to finalize the purchase there without going to the city. And truly the reason for going to the city is non existant, all we can do in the city is buy, because there is no social interaction like tap on their shops to gain social points and knock 3 seconds of their queued items or something similar like other games. Next piece of advice consolidate you mentioned fixed prices 6 times in about 10 sentances and that is redundant so my tip is to be concise and not write the same thing 3 different ways since it doesn't "prove or enhance" your point.
