I doubt “sold out” just the night right before they changed to no in store pickup they had every single model/color/size at all my 4 of the local stores around me. I think they just stop those prior and then reopen on Friday for in store pick up.

this was my experience too. sunday night at 11 pm all configurations were available for in stock pickup at all 7 nearby stores except 64 gb black 8. monday morning at 6 am when i went to actually do the order, all configurations were supposedly gone and no in store pickup on any of them, which im pretty sure was bogus.
