Sweet! Walmart has the LEGO Harry Potter Advent Calendar on sale for only $19.97! I bought this a few weeks ago for $25, so this is a great price. Since December has started, you could totally do this for a 12 days of Christmas, opening 2 each of those days. That would work out nicely if you have more than 1 kid too. Plus, use in-store pickup to save on shipping, or your order of $35 or more will ship for free.
