yeah, got lucky also once. But those deals are hard to find in any automated way. For an SSD you would need to do some sort of OCR on the label, if you can locate it. And then with all the stickers, low resolution, weird angles, OEM versions, and the 40 other numbers appearing on a sticker, not sure how many can be processed automatically. And you need to be quick. Some deals go within minutes of being posted. So those great deals are reward for people who are ready to really put in the time.
A few months ago on reddit there was a guy sharing a story of receiving the wrong server from Dell. But the one he received was packed with 24 60TB SSD. He called Dell who told him that unfortunately they couldn't locate his server, and asked if he wouldn't mind keeping whatever he received from them. He helpfully obliged!
