Summit no longer will combine both pro shop and 10% off coupons. Its either one or the other for now on. I placed an order January 30th and all went well but today they said no go. I canceled my 1450 dollar order and he called back later saying they would honor it on today's order as the coupon didn't state the new rules. In the long run it will probably save me money as I picked these up at car shows and races 3-4 times a year and felt obligated to use them. Thanks go out to Summit for all the good deals and helping racers thru-out the years. I've been dealing with them for 38 plus years.
