I know some yards to avoid, especially a certain lady at the counter (owner?) who nickle & dimes every tiny part. If they are franchises, then they are in competition so going to another enforces the hand of the market. I also find that if you buy a lot of stuff at once and checkout near closing time when busy (usually go together), they tend to be more lenient. If you show up when the counter is slow with just 1 or 2 parts in hand, they will price aggressively.

I have walked away leaving stuff on the counter when they price crazy, ex. Ecology asked $50 for the "blue saucer" and related parts I wanted to upgrade my 1984 to 1985 tranny controls. Got it later for $15 at a local PnP. I don't get mad, I just say, "I can buy cheaper on ebay, crush it".

I show them all parts, clearly bagged. If they beat me up, I just don't visit again. They need me more than I them, and they crush cars faster than people can pick them, so stupid to over-price.
