use shipping address as billing address is a common practice for customers who want to send items to a different address than the billing address associated with their payment method. This option is typically available when making online purchases, where customers can enter separate addresses for shipping and billing. It’s important to note that some retailers may require the billing address to match the address on file with the payment provider (such as a credit card company) to prevent fraudulent transactions. In general, using different shipping and billing addresses is an accepted practice for gift purchases or shipping to family and friends.
