I use to use Hyperwallet. They were really good, and I have started to
use them again. They do mostly bank transfers between canadian bank
accounts. Very fast and reliable. Not sure how they work with CC's or
internationally though.
I agree with buckaru. Most canadians don't even know the shipping costs
within their own country and are shocked when I bill them for it. I only
list on .com, really no point to lost on .ca unless theres a sale, but I
usually miss those sales becuase...
