A product kit is a series of items, grouped together, and sold in a discount. Product kits are available in the garage, and offer good prices even when a discount doesn't take place in the game. Significantly, kits allow players to buy items before the player's rank is high enough to buy the item separately. At any given moment, only some of the existing kits are offered for sale, each with an expiry time, and a range of ranks at which it can be bought. The price of a product kit is equal to the price of all the included items in it, with a discount applied on it, which ranges from 40% to 80%.
