Well, I can very well attest to the fact that it feels so good when you are successfully in purchasing game bundles. It actually gives you an edge in the game especially if the bundle helps you to upgrade your team.Some of the time some payment processing companies do offer the discount on the play store credits. And it can be pretty effective to use them later. So I tend to make sure of those games which offer the credits for such type of games or apps. It can be handy when buying other bundles and games online.
