If you don’t mind going on a little link hunt, you can easily get a full-sized free NeilMed Sinus Rinse bottle kit OR Neti Pot. Simply click through to where it requests your name and pick “p1886b” from the dropdown list. After that, you’ll be presented with 17 “slides,” which you don’t have to read and can quickly skip through. You’ll then be presented with a signup form and finally, a “quiz” where you have to get 18 out of 20 questions correct.
