Does Alamo require COSTCO coupons?

Alamo has never asked for any coupons. Iuse the 3 -4 times a year. I'm not an insider and use the kiosk.

I've found the Costco site to be very useful, but putting in your # is a pain (several screens), so I just use the discount numbers on the Alamo site. Never had a problem. When I arrive I go straight to the car and let the exit booth gal do the work (no counter & no machines).
Never been asked for my Costco card or coupons.
