There are a good selection of Ambulance Ltd cds to purchase on Amazon.com including some imports and rarities. Ambulance music is also available on iTunes.
New t shirts will be available in the Fall - in the meantime you can buy some vintage ones from Back Street Merch http://www.backstreet-merch.com/bands/ambu/default.asp?
Til we have new music out feel free to audio record the gigs and trade/swap your recordings with other fans. There are some bootlegs of the Ambulance gigs earlier in the year floating around featuring all the new songs .....
