Smile if you're Irish at Alamo!
I rented a midsize SUV out of SFO using the Costco Alamo code and also adding a $15 discount code I got on the Alamo website. I needed the SUV for 4 weeks.
Here is where the deal gets interesting .... if you select that you are Irish from the dropdown list instead of being a US resident, the rate for the 4 weeks dropped from $169 a week to $132.52 a week.. When I collected the car, they didnt ask any questions...
$150 savings over a month.. essentially a free week for saying you are Irish!
