20% off SOME Dorman products on Amazon $106.18

Hope this helps someone. Dorman makes a lot of repair parts for vehicles and I've had a lot of luck with them with the exception of an intake manifold for a Ford Triton 5.4L. I need front axle bearings for one of my vehicles and noticed the 20% off coupon which I don't recall being there when I was price shopping last week. When I click on coupon details it just says Dorman Save 20% with this coupon. Discount at checkout. I did a search of all Dorman products for my vehicle and it only applied to some of the products so I don't know the algorithm. Brings the cost of each hub/bearing assembly from $133 to $106. Considering I have 2 front axles that saved me ~$52 off regular pricing. FYI, Autozone has the part I need for $200 but the retail auto parts stores are for buying stuff you need now, not in 2 days. Pepboys usually offers 20% off on online orders which can be picked up same day making the prices competitive but I couldn't find the part there and like the convenience of a pre-pressed hub assembly because it takes the risk of some errors/damage out of the equation. Also, to get 2 of them I had to make 2 orders because when both were in the cart it only applied the discount to one item. https://www.amazon.com/gp/product...UTF8&psc=1 https://www.amazon.com/gp/product...UTF8&psc=1
