When my son was little he loved getting one big K’NEX set for Christmas along with his (requested) plethora of LEGO. I haven’t heard as much about the brand in recent years—maybe all the kids are too busy with video games?—but it holds a special place in my heart.

If you like to break out one extensive K’NEX set for the holidays, Amazon has this 568-piece Thrill Rides: Kraken’s Revenge Roller Coaster marked down to just $30 today (its lowest price ever).

The only way this deal could be better would be if it included an actual kraken. Preferably one that does your bidding on command. (Oh dear, I’ve said too much….)
