They were all made available for sale on Amazon at different times. Beyond members were also able to order the books a little sooner than standard retailers. My (un)educated guess is that since PHB was released first on Sep. 3, 2024 (early access via local game stores in Wizards Play Network and same time for D&D Beyond subs), a lot of those early sales weren't through Amazon.I assume they do, but not that this explains the difference. For 2014 there were around 1.8 PHBs per DMG, now there are 0.06, that is far too much of a swing.
Also, wouldn’t they buy the DMG and MM there too?
Then later on Oct. 29 (DMG) and Feb. 18, 2025 (MM) came out, more people were just waiting and getting them on Amazon.
