I have a prescription for a certain digestion aide which I need to take on a daily basis. A while back, I got a letter from my insurance that they will no longer be covering it and offering it through the pharmacy counter because it's an over-the-counter medication.

The problem is that almost nobody sells this drug in large quantities. I used to get a 3-month supply, 100 pills, for something less than $10. Now the best price I can seem to find is $12 for a 42-pack, and annoyingly they only ever come in incredibly irritating blister packs (a pox on the people who invented putting pills in those things!), or an equally unhinged option of being spread between three separate bottles and boxed together.

I did happen to find a place that sold the drug in bulk, but I've never heard of them and their website doesn't exactly inspire trust.

Does anyone know of a place where I might be able to find the drugs I need in quantities and packaging that makes sense, within the United States?
