For what it's worth, I have not bought anything in awhile from LD either. Mostly discount, and a private place for 25 years or so before owner retired.
Issue at moment with discount, is I'm trying to get best overall cost doing ALL the items including front end alignment due to a small lift, struts and having to disassemble front end parts....
Hence why to a degree discount is not part of process. I saw the new house brand tire at LS. Look like the coopers in many ways....
I've had, one of my son's has had the AT3 on our trucks, they've done well.
I'll post a pic tomorrow.
