The email will include instructions on how to purchase your single user OMA online subscription with a discount. Be sure to check your junk/spam folder in case it goes there instead of your inbox. The direct link to purchase your single user OMA Online Subscription can be found at the top of this FAQ by clicking on the link "Subscribe to the OMA online."
    • Please contact if you do not receive the Welcome Email 2-3 business days after renewing your AOAC individual membership or have additional questions. Allow extra time if AOAC is closed for holidays.

If you are renewing through Oxford for the first time, you will need to create a new Oxford account when you get to the cart page.
