Amazing value!

Just discovered this Member’s Mark version of the name brand at Sam’s. Checked the labels & ingredients are the same. The members mark has more pills for a fraction of the price! I always try to keep a box of these on hand during cough/cold season in Ohio. This will be what I buy from now on!

Congestion relief

Store brand Mucinex. This item was very comparable to the name brand. When checking the ingredients, you can compare side by side and there is no difference between the two. Excellent for those nasty head colds, congestion, and runny nose.
