2.99 UK Pounds a pop - I bought two and some other bits and pieces - this guy constantly turns over army surplus and these shirts are always available.
All right so not screen acurate but for that cost will make a decent safari shirt for the next Serengeti trip.
After reading this post, I went on eBay and checked out the "benfleetarmyshop" store, it seems pretty cool. Looks you came across something really great!
