Have you checked out prices on the broker lately? Zoinks! I've never seen so many 100M+ items. Setting prices one million plat at a time just doesn't cut it anymore. It's enough to wear out your mouse and your patience.
On the Patron server now is an update to the pricing window that adds an order of magnitude to Large Plat Values. So 100M takes only 10 clicks instead of 100. Still annoying, but much more doable. And less-stratospheric prices for the rest of us, like 20M or 30M, are a snap now.
Note that manipulating higher sales prices, especially when subtracting, takes many many hamsters to accomplish. So be patient while pricing those high-priced doodads. Your game hasn't crashed, I promise!

Thanks to Lhaffinatu for complaining about high prices, and for testing!
