Visit their travel site, even if you have no membership card, to compare their prices. You will see the four rental companies they use which has been Alamo, Enterprise, Budget and Avis.

However, to book you would need a membership. Using an executive membership gets you a better discount. Renting from Costco allows you an additional driver at no cost.

I have used them 36 times over the past few years. Most times my best deal has been from Alamo. And Alamo is the first renta agency on the first floor of the rental building directly across from the rental counters.

When I rent through Costco I usually begin my rental process about two weeks or more before travel. However, I follow-up weekly checking for a better deal.

My next rental starts on July 13th. My first rental reservation was with Alamo for 14 days was approximately $550. A week later my wife said she wanted an additional day. Cost $628. I didn't take it. Checked a few days later got the extra day no cost change. A few days later same 15 days cost now $528. The bottom line is I'm now down to $440 for 15 days, taxes and fees included. No cost to make new reservation or cancel old ones.
