First go to Advanceautoparts.com, shop for everything you need and get it in your cart. Once you know your total go here http://www.retailmenot.com/view/advanceautoparts.com
Find a coupon code that is closest to your total (ie - 30% off of $75 if your purchase is $84.29), copy or write down the coupon code, then go back to your cart and you can apply it at the bottom. Sometimes they offer free shipping on orders over a certain amount as well, but since I have one locally, I don't bother with that. Just make sure that all items are set to pick up in store, if you intend to do that, or it will automatically try to ship it to your address.
Advance posts coupon codes on there site too, but this is a better compiled list of working coupons, so you can get the maximum amount of discount off of your purchase. It has saved me A LOT of money on my parts and tools, I got a set of $55 ramps for $30, a set of 6 NGK Iridium spark plugs for $20, and ect. Hopefully this can help save you guys some money on parts, it's helped out a lot of my friends and family already
