Are you planning on renting a car in the US? Hertz has a $25 off a rental which is an awesome deal. You could rent a car for $25 or less and just pay taxes, so in theory your rental could be free or almost free. The main drawback is that this is per rental, so if you need multiple days, you’ll have to make one day reservations to take full advantage.

If you’re booking a car over the weekend, you could use RQ code: VSTPTE ($14.99/day.) A two day rental over the weekend would be $29.98 – $25 = $4.98 + taxes and fees. Certainly a steal.
