I spun my first pokestop of the day, seventh in a row, after midnight mass. And so I missed the first 1-use incubator. :-) When they said "morning," they meant... :-) Ah, well!

Thanks for the heads-up on the contents of the giftboxes, the math on the giftbox incubator value, and on the incubator color! So the incubators will look like running-out 3-use devices, instead of like distinct 1-use devices. Interesting choice!
