What are you paying for parts?

I work part time as a hiker(for a leasing company) on the weekends, so I see what the difference is between list/net price when I pu parts from dealerships. For example @ Freightliner- I pu injectors, harness, and some odds and ends. List price shows 1700.00, net cost my employer pays is 800$. I normally see the net running about 45% of the list price. What type of discount do LP's get from the volume discounts offered by the "purchasing power" of your companies?

 

Bumping this....
Looking for info on your fleet discounts, whether lease or independent. Added a few pics of the discount my company gets. Trying to get an idea of "buying power" for different outfits, as it will impact the bottom line.
