Thats pretty much the going rate for the FS2500 filter. Really not bad considering the filter ability and the longevity of them. Most of my customers go 80-100 before replacing them. UOA still look good at the highend mileage. Filtration Solutions doesn't leave much margin for the retailers to play much so the price between one place and another is minimal
You may check accurate diesel and see what they can do for a 3 pack of them. 25.00 each isn't bad though
