When you buy or save Google Offers, you need to be logged into a Google Account. This can be a Gmail account, or any other email address that you’ve linked to a Google Account. Each offer you buy or save can only be accessed when you’re logged into the particular account you used to buy or save the offer.
If you delete your Google Account at any time, you will be unable to access any Google Offers you claimed using this account. Even if you open a new Google Account using the same email address that you originally used to claim the offers, this new account will not hold record of your previous Google Offers. If you plan to delete your Google Account, make sure you print out all of your vouchers first. If you delete your account and can’t access your unused purchased vouchers, you can request a refund.
