Someone on this Board had an explanation for not shipping to AK and HI. I think it had to do with shipping taking too long and they were getting hit with "item not received" claims right away for Ebay sales.

I have never had trouble, so I ship to AK, HI, PR, GU, APO - you name it. APO can require customs docs, which can be a pain, but I have automated that through my shipping programs.
