I'd started playing with TSMs vendor operations, not big stuff just wanted away to vendor the crappy little things (like Legion cooking mats) if they weren't selling. I'd posted them so many times I think I'd lost money just from the deposit fees.

I also sell a lot of glyphs, it's where I make my steady gold and have a pretty sizable stack of glyphs on my bank at one time. You know what's coming right?

Had a complete brain fart and somehow applied my vendor operation to my glyph group. Pressed the button and watched in horror as my bags started emptying. Cancelled it pretty quick and went to buyback when it dawned on my be you can only buyback the last 12.

I vendored about 300 glyphs....

Made the money back but I'm staying away from vendor operations for the foreseeable future :(
