Mike's does take trade in's during certain promotions. Recently traded my entire DSLR system in for a new Sony full frame camera system.
Mike's Camera does do occasional used equipment purchases, especially when they're having a big event. Their Sacramento location has a huge Tent Sale coming up on 4/13 and 4/14/2018 and they will definitely be buying or trading in towards new purchases.
I don't believe that they do but Photo Source on Elvas Ave has a sign out front that they do.
