Thanks for the information and suggestions.. Walmart recently has been losing us in the system, sending prescription to wrong store,, limiting to 30 day supply even when last order was for 90 day, lack of medication in stock and need to order it causing up to two day delay, requiring me to wait til I am within 1 - 2 days of being out of med till they allow refill among other smaller frustrations.. This may just be part of living on the road but trying to find an easier way to deal with the issue.. Thanks for all of your input, may give CVS a try!
