About USMS Swimmer Mag Subscription

Has anyone of you received the May/June USMS Swimmer Magazine yet? I'm wondering . . . I'm not a member of this USMS Swimming organization (yet) but I got excited when I found out about the magazine. So I sent my magazine subscription request with payment to Douglas Murphy Communications (per instruction) last week of February. My account shows that the payment was posted on March 7. I wrote a letter to DMC inquiring about my subscription and according to their response they shipped the May/June mag in March 28. We're nearing the end of May and I still have not gotten the mag. Before I contact/write them again, I'd like to know that indeed the mag has been sent out and somehow I was missed. One would think that periodical shipping on March 28 should have arrived at destinations sometime in April. Don't you think? Thanks.
