I have found , regards amazon...I have been able to check company name, then contact that company directly. Check the company, and often when ordering directly company will also offer free shipping. Which is a concern to many.

Small business is 'stuck'? Recently researching safe sunscreens on ewg.org --found they were selling some on amazon. Receive a percentage I believe. Because amazon stopped selling or refused to sell important alternative books, I consider the company censorship traitors. Stopped selling NAC when it was recommended. Add those things to lack of quality control I feel amazon is not to be trusted
