Mail order prescriptions

Our insurance now insists on mail Oder only, I cannot even imagine trying to get the correct stuff through the mail, honestly, half the time I went to fill her stuff now, I have to tell them,oops, wrong size needles. Wrong test strips. Now that I have an awesome pharmacy, I will miss it! Plus the whole insulin in the mail, having to get it in right away so it does t freeze in winter bit is going to stink. Anyone else use mail order. Tips?
