I notice that Alamo's website lets you use the $20.00 off coupon in addition to a rate code (Walmart code 430710). I know alot of people on here have made their reservation using both, I just wonder if we will have trouble actually getting the car for that rate seeing as though the $20.00 off coupon states that it cannot be combined with any other discount? I am hesitant to book using both as I am afraid they will tell me the rate is not valid once I get there and then I will be stuck paying some crazy rate. Anyone have any thoughts or ideas on this?
