The cost of additional tabs in the new Guild Bank feature, which will be in the next patch, has been reduced. The last two tabs in the bank previously cost 5k Gold and 10k Gold; the prices have been halved, so tabs now look like this:

Tab 1: 100 Gold
Tab 2: 250 Gold
Tab 3: 500 Gold
Tab 4: 1000 Gold
Tab 5: 2500 Gold
Tab 6: 5000 Gold

To purchase all tabs, it\'s going to cost the guild 9350 Gold. Why pay that much? Well, each tab gives the guild an additional 98 slots - that\'s a total of 588 slots. Granted, most guild won\'t be buying all the tabs, but I\'m sure the larger, more successful guilds will be very grateful for this much space. The Guild Master is the only player able to purchase and name the tabs, as welll as specify who can access the contents. There is also a log kept of the past 50 transactions, so any shady dealing would surely be discovered.
