Advance auto is having a great sale. Spend atleast $100 and get 20% off on the spot plus a $50 coupon. Autozone was cheaper for my manifold though with 15% off and a $10 gift card with over $75 spent. If you need stuff these holiday week ends are the best time, I suggest you go to both sites add your stuff to the cart add the codes and see what is the best deal. I ordered my harmonic balancer from advanced and manifold from autozone. Just need the carb now
