I am constantly throwing stuff in my cart at Summit so when I need something quickly I can add the cart stuff to qualify for the free shipping. When the stuff comes I grab it out of the box and throw the slips in a pile for my tax returns. Well I needed a part number from something I ordered before so I grabbed my slips and started going through the ones from 2018 and there it was. A 20.00 off coupon on my next 100.00 order from a slip in January. Thank God its good till the middle of July. Check your slips guys and THANKS again Summit Racing.
