i find that my major, local auto parts stores have fairly similar pricings.
i prefer pep boys for my maintenance parts because their rewards card program is the best:
-1 point for each dollar spent, no minimum amount required to spend, after 100 points you get
a $10 gift card, and in the meanwhile they send you coupons for things like X% off a purchase
of XX or more, diy oil change special coupons, etc
also, pepboys has purolator filters.
i rarely if ever go to autozone, and their rewards card has a minimum amount required to
earn points (i think you have to spend at least $20?)
luckily for me, all of these places have military discount.
but, unlucky for me, Oahu, Hawaii (where im moving next week) does not have a pepboys.
well i stopped in to oreilly today to take advantage of one of their oil specials
(something like $15 for chevron oil & a filter) and i notice they finally have a rewards card!
its only a $5 gift cert for every $150 you spend, but hey its something.
you also get 25 points for every friend you recommend (who signs up)
as well as 50 points for going online and registering your card.
if you arent familiar with rewards cards, you dont have to carry them around, your
points can be tracked via your telephone number.
also, all 3 of these stores offer their rewards card for free.
