online pharmacies are cheaper

After Blue Cross and Blue Shield pays, I still owe $440/ month for one medication at my local WalMart for my daughter's anti-seizure medication. There are online pharmacies that are only $49 / month. Also, other countries have generic available whereas the US still requires brand name of certain medications. It is frightening to think of the fraud happens with online pharmacies. It is difficult to know who to trust.
My daughter wants to go through chelation therapy, but we have to wait until she finishes college I think because I don't want her to have seizures during the process. We are already changing anti-seizure medications which is scary enough.
