Amazing service

Very rarely to I write a review. After I placed my order, I missed a call from USP and then saw an email. One of the items I ordered was a new lower unit plug seal. I ordered one. They were asking if I needed 2 as the job on my Verado takes 2. Do you know how stupid I would have felt when in the middle of the job and realized I should have ordered 2? I sort of still feel stupid, but really appreciate the service from USP.
