I've heard many people claim it is possible but no proof. I don't for a second believe with the rate rupees drain that you can purchase something, wait as link holds the item, leave and re-enter, wait while the string is displayed, and still have time to grab another item. Maybe with the purchase of the blue ring but then you have an armos to contend with.
