Airport Car Rental PSA

Please excuse/ignore if this is common knowledge... but I am visiting Palm Springs for the first time soon from England, and felt obliged to share some info on car rentals that I have found.

I am not sure if this is true generally, but I was looking to book a car through Costco. I almost booked from one of the companies at the Airport - but decided to look at prices from non-airport locations...

... and they are literally 2/3 cheaper than the airport! Literally one third of the price!

I do not know if this is the case for other cities but wanted to share - the Avis location just around the corner from the airport was $150 for a one week rental - vs. $450 for the exact same car/rental but from the actual airport pickup location.

Relieved to have saved myself $300USD for just taking a 2 minute uber outside the airport - so thought I would share a psa for anyone in a similar situation. Cheers
