Might seem a silly question, but I'm wondering if this might be explaining some holdup on BTO rMB models. The reason I ask... I have a somewhat unique situation in that I've ordered from the US store, but chose a British keyboard. The plan is to collect it when visiting family in May. I ordered on 12th April, and my delivery slot is still showing as May 15-29 (I chose expedited shipping FWIW). There has been zero change in the status since.
