Sorry if already posted but just a heads up for trade-ins, my local Apple Store told me they can't do it in store since I preordered and had a kit sent to me. Same with my dad at his store. I thought someone had said previously they could still do it in the store but apparently that's changed this year.
It started last year at my local store. I would have to cancel the trade in kit in order for them to process it in store. Maybe other local store aren't enforcing it or it may also depend on the rep? I no longer select the trade in at preorder and just drop in to trade in the weekend after.
