Here are eight Lego Cyber Monday deals to check out. And don’t wait, as once Monday’s over, the deals go poof and disappear. (Oh and be warned: If a set says its on “back order’’ you might not get it in time for Christmas.)

Cyber Monday is your last chance to save big on LEGO sets before the mega-sales end. Lots of great sets are on sale from Star Wars to Harry Potter to Marvel and more.

Yep, in case you missed it, Amazon’s Cyber Monday Sales Event is underway, and the e-tailer also announced that there will be extended savings through December 3 with 12 Days of Deals. (Exciting news, of course, but heads up: We can’t guarantee that popular discounted Lego sets won’t sell out before the end of Cyber Monday!)
