Buyback currency items

[Rufalus]

I haven't played WoW due to it looking like a kiddy game so how about a little explenation about what you mean with this idea?

You can undo mistakes, like on gil shops if you sell something by accident there's a buyback option available (if you didn't leave the zone). Asking for a way to undo purchase mistakes on tome shops etc and get your tomes refunded, provided you have not used the item or left the area yet, some caveat like that.
