I dont know if this is a bug or intended but some times when i buy items from guild stores, i do not receive them afterwards with in game mail... if i log off and relog right away then i instantly receive them, but without logging off nothing happens. The most i have waited is 5-10 minutes but i dont remember this ever happening in any other MMO's. Its annoying sometimes because i buy items in order to deconstruct them and that means i have to log off/relog between leaving the bank and hitting the forge...
