How to work with special offers?

How the developer can work with our offers? He needs to ask our SDK about bonus or discount for the product (not bundle) before showing this product in any place in the game. The SDK return the data (discount/bonus, valid period and so on). And then the developer decides how he will use this data. The SDK always return only the best actual offer for the product (not bundle). So the game developer doesn’t need to check it himself.
