buying and selling the infinit stock items (bowls, vials, pots etc) will get you the same price no matter what. Player made stock is what changes and varies in price. as to the high alch shops- wearing karma gloves #3 will allow you to sell your items at karma shops only at high alch price but it will slowly decrese as stock increases. the bandit camp store, how ever, in the wilderness, will buy your items at high alch prices, no matter what the stock i believe, but you run the risk of pkers in a multi-combat area. hope this helps and good luck
