The lead offer on this page is the 20% off promo code for orders of $100 or more, and it is best if you plan to spend at least $100 on parts, accessories or DIY tools at Advance Auto Parts. There is also a 15% off code for orders of $35 or more that helps at lower spend, and several product deals that may beat percentage discounts on small, specific purchases.
Under $35: Use a product deal if it covers what you need. Many oil bundle deals start as low as $24.99 (ARGOS motor oil bundle) or $29.99 (Valvoline), so buying one of those bundles at $24.99 is cheaper than trying to use a percentage code that requires a $35 or $100 minimum. The 15% code does not apply because it needs a $35 minimum, and the 20% code needs $100.
$35 to $99.99: The 15% off promo code for a $35 minimum is the one to use. For example on a $50 parts order, the 15% code takes 15% off, leaving $42.50, so you save $7.50. The 20% code is not available until you hit $100.
$100 and up: Use the 20% off promo code for a $100 minimum. On a $120 order, the 20% code takes 20% off and leaves $96, a $24 saving; the 15% code would leave $102, a $18 saving, so the 20% code saves more once you meet $100.
Buying a branded oil bundle or kit: If you are buying a featured bundle such as the Mobil 1 bundle from $37.99, Pennzoil from $31.99, Castrol from $32.99, Valvoline from $29.99 or ARGOS from $24.99, compare the bundle price plus any built in freebies (filter, gift card, Stanley cup) with the cart total after any code. Bundles with a free filter and a $10 gift card can be better value than a percent off when your cart contains only one low priced bundle that would not reach $100.
Buying specific eligible items with rebates: Mail in rebates and product rebates such as the $15 rebate on Rislone DEF products or the $10 mail in rebate on Sylvania HID lighting apply only to specific products and in some cases are not compatible with other deals. The Rislone $15 rebate states it is not compatible with any other deals, so you should treat that rebate as the only offer on that product.

To choose between the 15% and 20% codes, calculate the total after each discount and take the lower total. Use a bundle or a rebate offer instead when it applies to the exact product you need, and obey any rebate rule that says it cannot be combined with other deals.
