I buy painting/prep items from

Hobbylinc.  http://www.hobbylinc.com/mig  It takes them about a week to ship, but they are good about getting products out to you.

Ammo Mig

Tammie's Hobbies in Beaverton, Oregon claims to have pretty much the full line of AK Interactive. They have some Ammo by Mig.

Sprue Brothers

Sprue Brothers has Ammo by Mig as well as a ton of other paints.  They list some AK Interactive books, but not paints.  I've bought from them before and have had excellent results.
