In my opinion, paying 6.5k per year really isn't that bad. But if you really don't want to pay, just keep some hammers in your bank. It'll use up 1 slot, but runescape members have what, like 500 slots? I keep a couple of each tool in my bank, just in case I ever need them. And yeah, if you are a free player, I guess it could use up some space. But yeah, I don't think 6.5k per year is THAT unreasonable.
