I'm currently renting (if you can call it that) a pulley remover/installer from Advance Auto. I was intending on purchasing it, but when he gave me the tool
I said: "Wait I don't want this one, it's been used."
He replied: "You don't want to keep it, do you?"
Me: "Well, I guess not."
Counter guy: "So just rent it."
Me: "OK, how much does that cost?"
Counter guy: "Just bring it back. You pay for it now and get your money back when you return it."
Me: "Really, so it costs me nothing?"
Counter guy: "As long as you return it."
Not the most profitable business model, but it works for me.
