Bargains for Armour Thyroid 23. January 2009 William Davis (10) We use Armour thyroid almost exclusively. I take it myself.

However, there are substantial price disparities in different pharmacies. For instance, in Milwaukee, a one month supply of 1 grain (60 mg) tablets costs:Walgreen's: $36.00Walmart: $9.54That's a considerable price difference of nearly 400%. It therefore always pays to do a little bit of shopping.
