If you run out of stock will you ever have more in stock before the sale ends?
TD seems to often run out of stock too quickly, on BF sales especially, even before your newsletter is sent out. I suspect you would get even more business if customers could preorder or you could ask the community's interest so that you have more units to move.
A year ago you gave us a second chance for those that missed Black Friday sale. Maybe do that again?
Or oh well, better be quicker next year. ¯\_(ツ)_/¯
