When you check your bank account or card statement, you may see pending payment authorizations. These authorizations happen so Apple/Google can make sure the card is valid, and to check that you have enough funds in your account to make the purchase.

These are authorization requests, and not charges. You don't pay for authorizations.

Authorizations may stay in your account for 1-14 business days depending on your bank. If you still see the pending authorization after 14 business days, contact your bank for more information. The authorization charge for Apple/ Google  is anywhere from $0.00 - $ 9.99, which is also usually the price of a full game. This is the reason it can be confusing.
