I know it's out of season but I think it's pretty rare for a lego advent calendar to be discounted this heavily.
From the webpage:
Make the countdown to Christmas even more exciting with the LEGO Friends Advent Calendar (41420). Each door reveals a new gift for kids to build. Each model makes for a great decoration, or all 24 can be played with together.
Kids’ advent calendar comes with a LEGO Friends Emma, Mrs Claus and 2 elf mini-doll figures, as well as a buildable toy penguin and a host of other cool buildable festive treats. Some models also come with fun, dynamic features.
Not only can kids use these models as decorations but kids can also play with each fun toy as part of a narrative theme – LEGO Friends Emma’s room, Santa’s workshop and a winter wonderland – to help spark creative play.
236-piece set makes a great pre-Christmas present for kids who want their fun advent calendar to give more than a fleeting moment of joy. The simple builds are perfect for youngsters aged 6+ to construct independently.
The box measures over 9” (25cm) high, 14” (37cm) wide and 2” (6cm) deep and stands securely when displayed. Kids can add the Christmas magic to other LEGO models they own because the awesome toys are compatible with all LEGO sets.
It was $25 there about 5 weeks ago and they couldn't clear them .
At least Camel picked that up :)
