We paid $46 in December for ours, and that was with the $10 off. We also got $50 off the cost of our Disney package in January (plus the 20% off value rates for our trip this August) AND a $25 gift card once we get to our hotel at Disney.
There are many places that AAA is accepted--hotels nationwide, local stores, etc.
Someone else said their local AAA didn't take the $10 off---but I wonder why you couldn't just sign up with ANY AAA office that currently has the $10 off? Or is that not possible?
