you are partial right - you really need to wait for full clearance to advertise.
it is also pointless to advertise until the product is on shelves (Amazon.com is not sufficient) in which case you can get CVS/Walgreens to assist in the costs of advertising
product placement through normal or social media though can easily say available via amazon.com or tryactipatch.com
