So if someone from outside comes to the vendor may offer the rapier of pain for 12k but if a member talks to the vendor he will offer the same rapier for say 50 gold or whatever small amount.
Now i can go a little crazy and say each guild vendor gets a small outside booth in aven. Even as I see price lists showing realistically its kinda tough in game to coordinate transactions, who is on when etc. but the vendor would always be around, and not just weapons potions,scrolls etc. soon we could start price wars together

Again I have no idea but the selling of items to the vendor can only be performed by members (or just officers) as to replenish his supply
Off the top of my head I am not sure if any kind of server reset would erase all his inventory or not.
Feedback? anyone
