You can still get your free NeilMed NasaFlo Neti Pot with 2 sample packets of nasal rinse if you haven't done so yet. You do not need to have a Facebook account, so anyone can sign up for this.
On the form, you will have to choose that you either; use Neti Pot currently, use another saline rinse, or are new to saline rinses. The first two will require you to fill out a survey, but the third one will require you to read some information and take a quiz. I recommend "Click Here If You Use Another Saline Rinse".
