well yesterday i had purchased a Banks Monster Exhaust. the website had it for 30% off and then they had a promo code for an additional 15% off anything over $99.00 . well when i tried to apply the promo code it didnt work. therefor i called customer service and i advised them of this and they told me that it doesnt apply to exhaust. so i asked if they would still give it to me, they said they couldnt do 15% but they would give me an additional 10% off. the customer service guy i talked to was awesome and very willing to make me happy...also FREE SHIPPING!! :redblob"
