I believe the reason that you don't see an option for in store trade in, is because there isn't an option to pick up your purchase in store yet. When I ordered my phone, I had done all the effort early, and put it in my bag. So when it came time & the option for in store pick up became available, I just purchase what was in my bag. When I got my phone the specialist did ask me if I had a phone to trade in, scanned it in, and told me I had said I would mail my trade in. This time I will be waiting to do all of that as the option for pickup becomes available, then see if 'in store' trade in becomes available.
