Sky Warriors/Store

The in-game store can be broken down into three main categories: Package Deals, Currency Purchases, and Item Purchases.

Package Deals
Package deals are offered daily, when you rank up, or when you unlock a new aircraft that can be purchased with credits. Rank promotion rewards usually offer a mix of lootboxes, currency (coins and/or diamonds), and items (missiles or flares, usually). They usually last 24 hours before expiring.

Package deals containing lootboxes are opened immediately upon purchase, and do not require a timer to tick down.

The Ready To Fly deal occurs whenever you unlock a new aircraft. By paying real-life currency, you will unlock the specified aircraft, a number of upgrades for it (making it stronger than the version you buy with coins), a paint job, and currency (diamonds and coins).

Daily offers usually contain lootboxes, coins, and diamonds. Their value ranges widely, though all cost real world currency.

Currency Purchases
Currency purchases are always available, and let you spend real life currency on in-game currency.

Item Purchases
Item purchases are always available. Unlike the rest of the store, item purchases are purchased using diamonds, not real life currency.

Though in the UI it appears with the other package deals, the store offers a single free item every 24 hours that can fit in this category. The free item varies from small amounts of coin (approximately 500), diamonds, missiles, or flares.
