frankly, the last time i actually saw tungsten film being sold at CP was more than 10years ago, when they still have dat big film fridge in their main shop where the apple cinema display is now. :think:
dunno if it helps, but you can try asking ah ying over at ruby if they can help u order. but, i think u need to order more than 1 brick to make it worthwhile for them to do it. occasionally, i know they do it for folks who want to order slide film.
