Agreed. I had an aluminum in Deep Blue with the blue braided solo band in my cart, but as I was hemming and hawing over whether that was what I wanted, my delivery date slipped from Sept 24 to mid October. So I removed it from my cart, added the same watch with a different band (blue sport loop) and got the Sept 24 delivery range again. The braided solo band itself could be bought separately and be delivered this week, however.i honestly don't think it is supply constraints it is the time required to pair the bands with the individual watches and then get ready to ship in time for friday... it seems apple picked a few limited combos of watches (for example silver aluminum with white sports band, space gray aluminum with black sports band) to have ready before the event and ready to ship by tomorrow for friday delivery. everyone else is delayed. this wasn't an issue in the past because apple left itself more than a week between orders and delivery but now they left themselves just 3 days. they will meet their claim of "friday" availability but the reality is only limited combos ever had a chance of making that date.
I’ll echo the sentiment on the price of those braided loops, however. Sigh. Wish they were a bit less expensive.
