Both are available to buy now, but Argos have reduced the price of the LEGO City Advent Calendar down to £13.99 from £19.99; Amazon are selling it for £17.99, making the Argos price the lowest around at the moment.
If you want one of these then I'd order one now - things like this don't stay in stock for very long AND it's currently available for both in-store collection and home delivery; it always seems to be the home delivery option that expires first.
Suitable for LEGO fans aged five and upwards (it does give an upper age limit of 12 on the box, but I know some AFOLs - Adult Fans of LEGO - who'd love this) the LEGO City Advent Calendar comes with 24 little LEGO bits and pieces hidden behind each door.
Christmas is sneaking up on us FAST; there are just 48 days left until 1 December!
