Editor's Update: The deal at GMG for $45 is kaput so the next best deal before tomorrow's release is GameStop. You can also opt for G2A which has the Origin key at around $43 after our coupon DZON --- although G2A is going with global EU release date of 9/25.
Pre-order bonus includes FIFTEEN GOLD PACKS over 15 weeks. GMG is an authorized Origin retailer. Pre-order keys are now being delivered according to Dealzon user in comments (thanks bk!)
Bonus items includes 40 FUT Gold Packs, Messi FUT Loan Player, adidas Predator Boot Bundle, Historic kit access and 3 extra goal celebrations.
