If you haven't heard of Singles' Day, here's a one word description to clue you in = "deals."
Lots and lots and *lots* of deals...all occurring on November 11th.
While in the United States it's still not as well known as other "shopping holidays" (like Cyber Monday or even Prime Day), it originated in China and is actually the b-i-g-g-e-s-t shopping day of the year worldwide and many US retailers are starting to offer deals of their own on Singles' Day...even if they're not all necessarily marketing them as Singles' Day sales.
