Costco Travel can be a great tool for finding cheap car rentals. The site has discounted prices for Alamo, Avis, Budget, and Enterprise. While anyone can search the site for deals, to actually book a car rental you need a membership.
Through February 8, when you buy a $55 Costco membership through Living Social, they will throw in a $20 Costco gift card, plus a few extra goodies:
- A free Kirkland Signature 48-pack of AA batteries
- A free rotisserie chicken
- A free Kirkland Signature case of water
- $4 off Kirkland Signature coffee
- $4 off Kirkland Signature albacore tuna.
Note that if you have a current Costco membership, you are not eligible for this deal.
