Whenever you make a purchase from the Coin Store, the Coins per package is increased by whatever your VIP level is after the purchase is complete. The store shows both the base pack level and how many Coins are added by the VIP Bonus.

At the top of the Store, your current VIP level is displayed. The purple bar underneath tracks how much progress you have made toward the next VIP level.

When you are in the Store, you can preview how a package will affect your VIP level by tapping the check box next to it. This will add a green bar to the VIP Progress at the top of the store, showing you how much VIP progress would be made if you purchased the selected pack.

If purchasing a specific pack would increase your VIP level and increase the bonus you receive with each purchase, the new bonus will be applied to that purchase. Therefore, all Coin packs in the store will update to preview the new VIP Bonus.

If you are previewing a large pack that will greatly increase your VIP level and then switch to a smaller pack that you wish to purchase, make sure to check how many Coins will be received from the VIP Bonus at the lower price point before.
