Crappy parts store voltage regulators

About two years ago, had an issue with Standard ign products VR's sold by advance. They were not internally grounded to the case. Only the little bracket to lock the plug was connected to the internals. Three of them in my local store, and two in a store 50 miles away. I called SMP to inform them of the issue, and was told " we know about it, we had a problem with our supplier". These regulators were still on the shelf 2 months later (huh?). A couple of months later I found their "fix", was to install a sheet metal screw into to case, with the head of the screw, contacting the little bracket. This allowed the case to be grounded to the internals, probably till corrosion ruined the contact. That is when I stopped buying anything made buy SMP.
Recently (About a year ago) got a bad fuel pump, did a warranty replacement, which was bad, also. All of the pumps they could get were bad in the box. Told "no refund only replacement". Haven't been in the store since. Called corporate, and gave them a polite ear full.
Also I have spent over $100,000 in that one store (commercial account), but now I can get a better price going online, and picking up the item in the store, then using my commercial discount. Loyalty? BS.
