When you create an account, there are many benefits that come with it.
1. Log In to see past orders and reorder with ease.
2. Having an account number will help the Customer Service find your account faster.
3. Easy to update email log in, change password, or update information contact on your account.
4. When people change that order and you can't find the Log In, Customer Service can track it down and update the information for you. See #2 and #1
