When I started ebay, the buck was ta about 62 cents, so it was great for me. It seemed people would not always take into effect the full exchange rate when bidding, and sometimes I would get some nice prices. (yes secret strategy is out). Plus the US is about 10 times as big as Canada. But then as the dollar started rising, I moved to ebay.ca so that i could have Cdn listed items instead, so I wouldn't lose on the weekly changes in exchange rate.
Now, in retrospect, I wish I would have done this alot earlier. It is just more plain and simple when all in Canadian currency. I have found that 99% of the notes about went to Canada, (although coins were a different story). The thing is, if you list on ebay.ca, your listing STILL shows up on ebay.com!!!
I wonder if everyone knows that fact. If not, it should work for most everything.
But in general, ebay.com may bring in more people in general. But it is basically all one and the same. I have been basically off ebay for a while due to other commitments such as University, but in the future, I still definitely prefer to use ebay.ca.
plus, you dont have to lose on the buy sell spread on your fees either (which would be in US $ if you listed on ebay.com)
