Discounted Battlefield 3 Premium Edition expansion packs for $24.99 from Origin
EBGames was the next most competitive price I could find for this edition at $28.99. At other online retailers you're looking at paying $40 from JB Hifi, $46.99 from Ozgameshop, $49.99 from Fishpond.com.au and Play-sc.com.
This edition includes expansion packs to Back to Karkand, Close Quarters, Armored Kill, Aftermath, and End Game.
You'll also get access to the exclusive Battlefield 4™ Beta.
