I support this. As an ironman, the items that are available from the Slayer Point Store is limited and not really helpful. In saying that, I don't want it to be over the top so one of us can just do slayer and get all the food he needs for the rest of his life in a day. The prices of food/potions (if such items are added) need to be discussed carefully do provide a good balance between the slayer point:item ratio.
Great suggestion, I hope it gets considered. :)
