WOW! seller EJSE offers an amazing bargain
I take these for a nagging cough and to thin mucus that my chronic allergies burden me with. These are so easy to take compared to the liquid and I like how long they last. The cost is a drawback, but I need relief, so I've paid a lot for these from various sellers. When I saw the listing with EJSE's low, low, low price I was astonished and very glad. How can they sell at their bargain price? I found out an answer to that question: they are a small, family business and their overhead costs are much less than larger corporations (they sent info about their company with my order). My order arrived very quickly and yes, they are what I needed. The box was unopened and showed an expiration date about 18 months ahead...that's 1 1/2 years! Yes, I do recommend these and EJSE as seller. I will be sending another order when these run out in 2021.

So grateful to have found Mucinex DM
The product arrived well protected. I had been getting them from Sam's Club. This order was so much better. The ones I have been buying are BIG. These are so much smaller and nicer. It's a good thing I swallow pills well for the ones I have been using for years! And I didn't like the generic at all. I think they compare well with a drug I was able to get by prescription for years and nothing I did get after that, non-prescription and not like Rutuss. So happy to have found them at Amazon. Great merchant.
