I am constantly running out of medication because they use DHL. For example, I ordered one refill as early as my insurance would allow. Ordered 12/31, ran out 2/13, haven't seen a status update since 2/11. I was without a very important medication for 1.5 weeks the time before that. I know you can do better with domestic shipping. You can't blame it on "supply chain" when my order was supposedly packed and put in the mailbox 13 days ago.
