My wife can usually score some kind of deal almost anywhere with the different programs she is involved with, but the one thing she has never been able to score me any is real discounts with Summit, Jegs or Speedway. The only way I have ever scored with these three is indirectly when she is able to get cash back on our credit cards. I am amazed how much money she is able to get us in cash back. We always pay them off every month, but they will offer incentives if you spend so much by such such date. She will simply move some of our normal and recurring expenses to those cards for a couple of months and bam-cash back. Normally, we don't have to spend any more than normal but there have been a couple of times when we needed to spend to get to the threshold, that is how I got new tires and wheels on the Duster. She probably made $3k last year on those kind of deals.

Summit will price match. If you can search around and find what you are looking for cheaper they will match it. I just bought a AEM air fuel kit from them, that they matched to a price I found on eBay. It saved me about $50 (25%) and I have the ability to return if anything happens. The things I like about Summit is the quick shipping (2 days for me), pricing and their customer service (returns), they have never failed to take a return or make it right.
