I believe you on the retail floor sales. The upsell is subtly built into the pricing and configurations. MKBHD describes this well here:
I noticed this more as I worked the Genius Bar for a couple of years (UK) and the pricing was outrageous and coverage for some things refused, for example liquid damage on Apple Watch which was advertised as water resistant.
Frequently priced very close to just getting a new one on many accessories like Watch, AirPods, lore end iPads.
