Head to Facebook and become a fan of NeilMed Sinus Rinse for a $3 coupon and a $4 mail-in rebate on NeilMed Sinus Rinse.
I’ve never seen this product in stores but it retails for under $5 on Amazon.com. You can’t use the coupon at Amazon but you can submit for the rebate so this rebate results in a cheap or FREE product from Amazon or potentially a money-maker in stores when combined with coupon!
