So which Apple promo specifically are we discussing?
In general, Apple doesn't offer promo pricing, though sometimes they will throw in an Apple gift card if you buy one from column A (say, a laptop) and one from column B (say, Air Pods). They also offer, every year (repeat: every year) a smallish freebee of some sort if you buy your college-bound offspring a MacBook of one kind or another over the summer before the kid leaves for Old Ivy or Enormous State U.
Apple authorized resellers such as B&H, Adorama, Amazon, and the like regularly offer a pittance off the Apple list price on Macs, but again, I (and I may be getting hazy with age) haven't noticed any increase in the frequency or size of those discounts this year, or indeed at any time during the pandemic.
Disclaimer: I get too much email from the Cupertino Fruit Co. (I was going to type "far too much," but then I thought of all the email I get from political candidates and their friends every hour of every day in an election year in the US, and realized there was an order of magnitude difference), but I'd know if they'd offered serious discounts on anything. But Apple just doesn't do that. They might eat an unaccustomed hit to their much-celebrated net margin on a given product if there are supply chain-related increases in critical components (as is currently rumored to be the case for the mighty CPU chips in their iPhone 14 Pro and Pro Max), but the prices rarely go down for any line of product; indeed, they got kudos from the media for not raising the price of the current crop of fondletoys in a year of 10% inflation, continuing supply chain issues, and mainland Chinese missiles flying over the island where all their CPUs are manufactured.
