I am having the same issue, and it's driving me absolutely nuts. I would love to be able to use auctiva for my listings, but if I can't get US funds Im forced to use ebay to create listings.
I only have the c$ or $ option.
Yes I have tried Mikes work around option, but when I try to preview it is always in CDN$.
P.S. I love auctiva, this should be a really easy fix.
