My husband printed out a evaluation by Fidelity this morning for me.

I can't find the link on the net....

but basically, it says that Target has already said it will match prices
in the Tampa area, etc.

CVS fell 8.4%, Walgreen's down 7.4%, and RiteAid down 5%...
with this news... so everyone is really upset.

Many mom and pop stores do sell generics to cash customers already,
reasonably... this is only going to affect the older most widely used drugs.
Some old generics that were all bought up by one company like
chlorazepate, lorazepam, and hydroxyzine, probably will not be covered.
Those companies raised their generic costs hugely by controlling the availability of the drugs. (Mylan was sued for this).

The article states that generic manufacturers and wholesalers also lost value yesterday stock wise.

So it will be interesting what develops with this.
