Apple absolutely does, especially from their own certified retailers like BestBuy or Amazon.
Do you honestly think that Best Buy and Amazon set their own prices? Of course not, that’s why all the deals are usually so aligned just right.
Same goes for Walmart, Apple is literally producing new inventory of the old M1 MacBook Air * Specifically* for Walmart to carry it at that $650 price point.
Same for the iPad ninth generation, which is still being sold new in several places, despite being discontinued over two years ago.
