Anyone ever successfully use a Jegs discount code?

I've never gotten it to work, too many brand exclusions, any item that's on sale, even if its .49 cents off, they subtract the items total value from your being able to meet the $500 threshold to get the $50 off. I'm ready to go back to Summit, or Speedway, or Rockauto, or whatever.
Jegs codes basically stopped working the Moment they sold the business. It’s a bait and switch. They toss up all those spend 500, save 50 or whatever. But then they at the same time, do a “sale” on 75-90 percent of their stuff, usually just a few pennies on the dollar, but enough to block the codes.

I stopped ordering thru them
