Does anyone know the cheapest place online to buy Physan?

Thanks for all the informative replies you guys truly amazing! I think i'm going to try and place an order for an 8oz bottle on ebay and hope for the best. I would really be interested in any easy to acquire alternatives for us canadians though also i was wondering if anyone knows of a long acting fungicide?? plant preservative mixture works wonders and lasts a year but it is soooo expensive... so if anyone knows of another fungicide that works for a long amount of time (at least a few months) without the need for reapplication. paclobutrazol works if your willing to deal with slowe growth times but that is something i would like to avoid optimally...

Thanks again for all the help everyone!

Best regards,
Kevin
