Ultimate Team can purchase either coins or FIFA Points. FIFA Points are sold in bundles and can be purchased in the Ultimate Team console store with Microsoft Points or your PSN Wallet.
FIFA Points simplify the purchase process for users who buy multiple packs. After buying FIFA Points on your console with your respective currency, they will be available to spend in the Web App and future extensions of the Ultimate Team ecosystem.
Purchasing larger FIFA Point bundles gives you a bigger discount and more bonus points. This offers great value to users who buy several packs in Ultimate Team.
