Advent calendars rank among the most desirable gifts of the holiday season. The difficulty lies in the fact that they need to be given out at the start of December to follow the tradition of daily openings, which reduces your shopping timeframe by a few weeks. Unsurprisingly, there’s a scramble to purchase them — thus, when Amazon provides limited-stock Advent calendar promotions ahead of Black Friday, it’s prudent to seize the opportunity.

As of Nov. 11, we have come across an exciting range of Advent calendars extending beyond the always-popular Lego sets that frequently sell out. Themes include Mini Brands, Bluey, Hello Kitty, and various Disney Funko Pop! items. Some are flash sales with restricted inventory, so if you spot one that’s still in stock and discounted, make sure to snatch it up.
