The right hand has no idea what the left hand is doing. My supplies not shipped on time because they say my insurance hasn't given them authorization, yet they sent me supplies the previous month... this is only my second order... insurance says they have, no idea why they aren't sending... now I'm without supplies. They notify me of this via email AFTER 3 weeks of placing my order. Just getting things set up with this company was such a cluster. Go elsewhere if you can! Fair warning!
