If your goal is to foster open-ended play and get as many LEGO bricks as possible for the least amount of money, here’s your deal: Right now tucked in amongst their Cyber Monday deals, Jet.com quietly priced this LEGO Classic Creative Building Set of 900 (!) pieces at just $24. (For reference: it’s currently $46.75 at Amazon.)
Now, the deal with Jet is that you’ll get free shipping on your $35+ order, so you’ll want to find something else to get to that threshold, but the good news is that they sell just about everything, so I’m confident that if there isn’t another Cyber Monday deal you want, you can find some dish soap or snacks you normally buy, anyway. And the more you buy, the more you save.
