Found a Dollar Tree with lots of Mucinex Sinus-Max Day/Night Value Packs on the shelf! You can either use an $2 any Mucinex product or the $2 Mucinex Sinus-Max coupon from 2/24S and get your products for low tax. They also had another variety (think it was daytime), but this was more bang for the buck. Coupon expires 4/7; product expiration is 06/2019.
