I took my truck to an AAMCO on Cave Creek and Cactus for service, I was quoted a price for the service. I picked up my truck when service was done and tried to present a coupon that would save me 10% which is $73.70 and the owner (Steven Becht) said he can't accept the coupon because he gave me a special rate to begin with. I would assume when you accept coupons you have to take them from everyone, you can't turn one away claiming there was a special rate given. It's unethical and probably illegal. Also they claim they discarded my parts right after working on my truck therefore they couldn't give them to me when I picked up the truck 6 hours after it was worked on, which give me the impression that they sold me parts they didn't put in and just adjusted what I had. (transfer case chain and sprockets)
I am out $73.70 that should have been entitled to me with the coupon.
