I have had all manner of strange things happen with my Dragon and Dungeon subscriptions here in Australia. Originally when I first started subscribing I got the issues before my FLGS. Then after I had received a couple of issues of each magazine they just seemed to stop for a while. I got nothing for a couple of months. I e-mailed Paizo and got no reply. The second time I e-mailed them I did get a reply. Wade from customer service was very helpful and said that he would try to sort the issue out for me. A couple of weeks later I received 2 issues of Dragon and 2 issues of Dungeon in a short period of time. I was still behind my FLGS but at least I was getting issues.
Then it happened again. I got nothing for months. At one stage I think I was 2 Dungeon issues and 3 Dragon issues behind my FLGS. And keep in mind that this is in Australia so the issues in my FLGS are already at least a month behind the US. I e-mailed customer service AGAIN and he sent me out 4 issues (1 Dragon issue had sold out). These copies reached me in less than a fortnight. Then like magic the 5 issues that I was behind started turning up on a weekly basis. I ended up with doubles of 4 issues.
Since then I have found it to be a feast or a famine. I will get no issues for a while then 2 of Dragon and 2 of Dungeon will show up in the space of 3 weeks, still later than my FLGS however. It is because of this that I am not renewing my subscription. The whole reason for me getting the subscription in the first place was to get them earlier (which did happen to start with). After a while I just started to hope that I got all of the issues that I paid for. I figure I'll just buy the issues from my FLGS in future. They need the support and at least the supply is regular.
