This deal is part of Target's regular-as-clockwork 20% off Lego sales, which happen every other month these days.
The full catalogue is available here if you want to check out the other Lego deals.
The most notable deal in the 20% off sale by far and away is the Lego Star Wars Tantive IV for $263. Apart from Target, it's still a Lego [email protected] exclusive and still going for its launch price of $329 there.
A 1,768 piece set that's 62cm long and a great re-release of the previous Tantive IV sets from 2001/2009. The most detailed of the three by far with the most accurate proportions.
Everything else in the catalogue is an average deal at best in terms of price, or worse than recent deals for the same set or current eBay pricing.
