Atlantis is at the end of it's run and Toys'R'Us Canada is clearing out the largest set of the theme at half off. As a big fan of Atlantis I really enjoyed the 8078 Portal Of Atlantis set I think it's a no brainer at $64.97. You can also score either the 8083 Rebel Trooper or 8084 Snowtrooper Battle Packs at $7.47.
At the time of this post the three sets are out of stock online, but I have little doubt you'd have trouble finding them in store if the pile I saw at my local TRU is any indication. There's also a 25% off deal on all LEGO lights, 20% off all Pirates Of The Caribbean sets and a FREE LEGO Ninjago 3D Battle Arena with spinner with any $50 Ninjago purchase.
