i go to PNP type yards once a week and around here (middle TN) they only have a environment charge, i forgot how much exactly but it isn't much. plus when i come up to the counter with a bunch of stuff they don't even charge for the little stuff and most times the clerk is so unknowledgeable about the parts that they don't charge for the right item (example: today i pulled an exhaust manifold off an OM603 and even told the clerk it is an exhaust manifold (their list is $20) but he gets out his tape measure and rings it up as just plain exhaust pipe and charges me $6) also at this other yard i found a bunch of new in the box parts (water pump, fuel filter, trans filter kit) and chick at the counter said they don't have a "button" for new items and just lets me have them for free...i love self service salvage yards!
