Cummins part prices are generally not too bad, comparing with some truck dealerships‘; with 20% off even better. A few days ago I went to one of their locations, to get a few o-rings and special washers. Their prices for small o-rings were about $3.5 apiece. They didnt have one of what I needed so told me to check Kenworth next door. I did, and paid $6 for a similar size one
