O'Reilly Auto Parts: $5 off a $5 purchase!

I don't know about you but I love to get coupons to places that you would think coupons don't even exist to. O'Reilly's is one of those places!
Right now, on their Facebook page, they are running a promo called the Cash Countdown. Every day they're giving cash away to welcome in the new year.
Now through the 30th, 3 lucky winners will be chosen everyday and will receive $500!! And on the 31st of December, 1 lucky winner will be given the grand prize of $1000!!

Just go to this link and like their page. Fill in the information and allow them to access your wall in order to get an entrance to the contest. It doesn't stop there though. Just for entering you will receive a coupon for $5 off your next $5 or more purchase of regularly priced merchandise.
The offer expires 1/31/14. Make sure to check your junk mail if you haven't gotten your email, that's where mine initially went.
