For some of us, the amount of silver the current available purses hold is a pretty large hindrance. While 7500s seems like quite a large amount, those Banker's Purses get filled rather quickly when there isn't much to spend your silver on.
I suggest a new, larger purse called a "Tycoon's Purse" or you could call them "Mr.Tuggle's Purse" . This would cost 2k silver, but hold 20,000s.
Either that or put a working bank in the game please
