I'll bet the small print will also say can not be combined with other offers.
No harm in trying, but I doubt that you can. If you find yet another offer, maybe they will pay you to let them do your servicing for free!
Read the fine print, it will usually say one offer per customer per visit, or something to that effect.
I work for AAA Roadside assistance, and sadly you cannot
I am a AAA member and I'm told I get $15 off oil changes for being a member, but I also found a $15 off coupon. Can I combine these discounts so I get $39.95 - $30 = $9.95 oil change?
