Are new parts crap?

I have gotten my fair share of bad parts I paid $100.00 for a water pump housing from 440 source which was in horrible condition and would not allow the pump to seal on it, got a set of $150.00 Bouchillon Performance pulleys, that were 1/2 chormed and stamped made in tawain on them put them on my motor and they clanked weren't even close to being true. It's not always the parts sometimes it's the distirbutor. Last Thursday I ordered and New cam, intake and all the gasket to go with it, I paid for overnight shipping so I could get the motor back together on Friday and to the track on Saturday. Well guess what, they sent me the wrong valley pan, very frustrating as no local shops stock them, couldn't it have been an easy part to get? Just got the correct one today a week later that was summit. So I was so mad I decided to give Jegs a try Monday I ordered a set of autometer sport comp gauges, got them today and it was odd two of the 3 gauges were in funny jegs boxes marked for internal use only, the other was in a nice sealed autometer box. I opened the "strange" jegs boxes and these gauges were obviously used parts (scratches missing parts etc) that had been returned. I have no problem with used parts, providing I pay a used price and I know what I am getting. I immediatly called Jegs they argued with me for few minutes asked me to send the gauges back at my expense, finally I got a manager and they are overnighting me new gauges, with a call tag for the old ones. It's amazing to me I am in a customer service and sales position, if I treated my customers like that I would be out of business.
