Cheaper than parking? Possibly
This hack makes a lot of assumptions, and could still end up costing you money. I cannot imagine a world where such a service is free of charge, but I will play along. This poster states that if you are concerned about expensive parking, find a tire shop, get your tires rotated and ask if you can pick up your car later that day.
Apparently – this has worked for them, but I would love to know if anyone else had such success. This could be possible, assuming the rotation is free and the shop is located near your destination. Gamble much?
