i just recently switched to levemir and novolog flexpens. my doctor gave me two cards that help pay for 4 fills. i was kinda sceptical< but, i got 2 boxes of each insulin and with my insurance copay and the cards i got them for free. apparently it pays up to 50 on the first rx and 25 on the next 3. you have to have a different card for each and must call and activate them, but to me its well worth it. just thought i would share.
