I know the cost problem. It has definitely been more expensive to buy DVD's for Iraq than it cost to send VHS to Kosovo. I shop Wal-Mart and get preused at Hollywood video mostly.
I had only one request for music, and sent over a bunch of my classical and jazz tapes, and bought a couple CD's.
I'm sure music CD's are tops in interest, but it's hard to get them to tell you exactly what--they have a lot of other things on their minds I think.
The last boxes I sent I included a questionnaire for requests from soldiers around them, so maybe we'll get some more specific information.
The box to Mosul had some suggestions from soldiers in it, which is why it had foot powder and toys. Kosovo depleted my entire collection of action, etc. films, but I was glad I had sent them as the 101st Airborne and the 10th Mountain later went not much later to Afghanistan and then Iraq, and I hoped they carried the memory of someone caring about them before 9/11.
With a couple dozen faithful others I call the Merry Band of Patriots we sent over 150 movies to Camp Bondsteel, and they and the boxes of Snickers candy bars where the most appreciated gifts then.
I just got back from Block Busters .. there were having a sale on pre-viewed DVD's .. 3 for $25
I'll be sending them off to ya
