I hope I am wrong, but from looking at my trends compared to past holiday selling, the trend has slowed already. I would not be all that surprised if people stopped online buying a bit earlier than normal this year because of supply chain shortages and possible shipping delays.
I hope I am wrong, but I am seeing a bubble in my sales that started to burst over the last three days. This is looking at data from all of my selling platforms, not just FAA, and the trend line is precisely the same across the board, going south.
I am not trying to be a downer, just reporting my own finding on my own sales. At this point, I would suggest that the strategy would be to forget about deadlines, forget about sales, and just push out as much advertising as possible, and let the rest take care of itself.
