$20 Off Royal Purple 5qt 0W-20

O'Reilly Auto Parts has the Royal Purple full synthetic motor oil 5-quart for $19.95 after applying a $10 email coupon and a $10 rebate. The deal includes an automatic coupon for $39.95 and a rebate, which combined reduce the price significantly from the usual cost. To redeem, use the email coupon code at checkout and submit the rebate after purchase. The deal's final effective price of $19.95 is a notable discount, especially considering the typical retail price of synthetic oils, which often exceeds $40 for 5 quarts. Although the deal may vary (YMMV), it offers significant savings when the rebate and coupon stacking are successful.
