Yes, through eBay. I'm one of eBay Canada's sellers. They're touchy about releasing the numbers of how many sellers they have. I'm under the impression that it's in the hundreds of thousands just within Canada. I don't know how we all rate against one another. I can't pretend to be a $15-million-per-year entity. My revenue is much, much lower.
Even though I could qualify, perhaps, for one of the lowest tiers through solutions for small business, it's easier for me to just stick with PayPal shipping, which has negotiated its own arrangement with Canada Post. That's the discount I use.
