Hah! There is an entrance to a dungeon that had 6 pots just inside the dungeon zone in. They always had the same items totaing 34 or so rupies. I think I went in and out of that area 1000 times.. FUN FUN! go Nintendo
See there is just one more part of poor game planning. You don't make enough rupies threw playing through the game to even be able to afford half the maps so you are forced to all sorts of unfun crap.
