I'm going to assume it is whenever their BF prices start online. Looks like that is Monday the 25th.
I get them every year and that is when I grab them.
They did have them at BF prices right after the ad came out so I'm guessing they won't do it again before BF week.
The fleece throw blankets? I always buy them as teachers gifts and they are usually the lowest price they will be during the black friday sale. It looks like they are on sale for 8.99 and then you'll get an additional 15% off during the sale.
