I've ordered from Dell and Supermicro (and others, but not in volume or often enough to have much data) for a couple decades now.
Supermicro you consistently get a good/best price. It's already pretty low, so going from a 10 unit order to 1,000 unit order gives you some discount but nothing crazy most of the time.
Dell it's basically based on phase of the moon. I typically tried to time my smaller purchases to coincide with end of quarter. Wait for my rep to call me and ask if I had anything for him. If my little 6 unit order helped them or their boss hit whatever target you could get amazing deals. Stuff where they wouldn't budge 2 months earlier could be had at below supermicro pricing. More than a few times they would give such ridiculous pricing that I considered ordering way more than I needed to part out the components on eBay and just recycle the sheet metal and motherboard.
Other times/years (and different reps too!) would give a budgetary quote for a build and say they'd match a Supermicro quote which was nice, but took extra work and never feels great when you know you're using a vendor just to get pricing down with the one you actually want to go with.
I just hate dealing with that junk, so I tended to prefer Supermicro to reliably get decent pricing when I needed the gear vs. having a whole strategy around order timing.
Then you get into stuff like hard drives/SSD and that was a whole thing w/ Dell for quite some time. These days they are competitive but they were not always.
