can we raise the amount of eggs you can buy at a time from 500 to 2000 so not have to sit there and hit the buttons so many times

Allow people to buy the market out, if you have the silver, and the CM space you should be able to buy all 3m of a listed item.  IMO Max buy amount should be amount listed + Max pre-order.  Inversely Max sell amount should be amount of preorders + Max amount that can be listed at a time.
