The 2,314-piece R2-D2 display model was officially retired by Lego in January, so this set was already hard to find.

Right now, the LEGO Star Wars Imperial Star Destroyer can be obtained for just $111, down from its regular price of $159. This huge 30% discount marks a new all-time low and with over 10,000 units sold in the past month alone, this set inevitably might sell out soon.

One of our all-time favorite sets, the Millennium Falcon Building Set, is now 20% off. A popular replica Animal Crossing set is now 56% off ahead of Prime Day. The Young Simba replica building set from Disney is now a whopping 50% off for the last day of Prime Day.
