The charges pending from Google are actually pending authorization requests between our billing system and your credit card-issuing bank.
Authorizations are the initial communication between our billing system and the bank's billing system to ensure that the necessary funds are within your account before the amount is deducted. Google will not bill an account until we receive an approved authorization from the bank.
When you check your bank account, payment authorizations will often be listed as pending. These charges might remain in your account anywhere between 1-14 business days, depending on the bank.
Sincerely,
Carolyn
The Google Checkout Team
