This small addon sells all useless gray items in your bags whenever you visit a merchant, so you don't have to search for them all the time.
Warning: If you use some grey items that you don't want to sell (for example Rusted Pitchfork for flex), do not use this addon! It has no filter settings so it WILL wipe ALL your grey quality items from you bags. You have been warned!
I will do my best to keep it updated, but I no longer play WoW so it takes some time before I hear form someone that my addons are outdated. If you notice the addon is out of date just email me: markyxll at gmail dot com, and I will try to update the addon when I get to it. If you wish to give me some motivation to fix it ASAP or if you just wish to thank me, you can send a few cents via paypal (the donate button on this page below download).
