We're making different points.
The @AnkerOfficial post at the top is in the morning, it might have been very early like 00:00 midnight or soon after and if so then factually it is 24 hours and 1st to this forum. So Anker may well be factually correct.
Your making a different point that you didn't get the email til evening.
So kind of 24 hours sale, told to community first where it may well have been then 24 hours of notice, and then progressively told in more ways through that 24 hour period.
I'm making the point that a USA-only offer beginning at midnight when most are asleep is in reality not 24 hours, and given we may not look in the community first, in all practical senses its available to everyone given its on Facebook like 6am and then on deal sites soon after.
For this to be community only, rather than community first, you'd need it just in the community and nowhere else. That isn't what happened here, it was community first, whilst we mostly asleep and then when we wake its for everyone, so in all practical sense there was no real community advantage.
Regardless, there was a whole day to notice it in many forms in this community then FB, then email, etc so plenty who were online had a long time to look notice and decide if to buy. In my case I noticed it about 11am I think and wasn't interested as I have all the items I want of that type.
