For a while now, we've removed the shipping charge on orders shipping to APO addresses: it's one small way of saying thanks to the folks who serve this country. We didn't tell anyone we were doing this -- it's just something that we, on the fly, decided was the right thing to do.
Now we've made it official: during the checkout process, you'll see the Priority Mail [Free to APOS] to shipping option if you enter an APO address. And just because it's free doesn't mean your order will be delayed or sent via a slow shipping method: it'll be the same fast service everyone gets.
By the way: when we introduced our Brain Bag backpack in Universal Camouflage, we offered customers in active duty military the option to swap their current, non-camouflage Brain Bag for the Universal Camouflage version. That offer still stands. Email us for details.
