Domestic (US) shipping is free!
Canada and Mexico - almost always free shipping (under $39 is $12).
Other international - almost always free shipping (under $39 is $15).
I ship Priority Mail in the US and Priority Mail International elsewhere. For international shipments any duties, etc. are not included and are between you and your customs agency.
APO/FPO - These addresses are fine by me, but note that I check the customs restrictions. As a practical matter, if you're in the Middle East I probably won't be able to send you your prints (Most everything on this website falls under the E-2 restriction - they don't care that it's art.) In that case you'll need to specify a domestic address. Feel free to ask before ordering - I'll need your zip code.
