Best Buy currently has a trade in option for last gen iPad Pro’s (10.5 and 12.9 ver.) to current new iPad pro’s. It’s kinda vague as far as what your getting says in store only. But, it shows iPad Pro from 399 when you trade in any working iPad Pro. Anyone have any insight to this? Looking for a 12.9 (64gb WiFi) to upgrade from my 10.5.
