Ah, an ongoing deal then. Well, regardless, at least I was able to get a discount and share the offer with others who might be looking to purchase a Mac Mini M1.
Just noticed this deal is back, and the 512GB storage version is now $749, which is $150 off the full retail price of $899 ($120 off their regular price).
AAFES (US military store) just had a sale of the M1 256gb for $499 with no tax. So for the military/veteran types, always good to keep an eye out there.
