My site domain name ends with a .ca. i.e Canada
Does that mean I don't submit to Yahoo Global dir ?
I sell software in Canada though we sometimes get customers from U.S as well ? If I ' have' to go to regional , is there a point/boost I can get via regional ?
The question is to pay or not to pay ?

if you got the cash and dont mind you can pay for it, i dont like the yahoo directory since i heard of their' no refund' policy, but if you submit your site to yahoo they list your site in different regional of their directory too.

so no use then ?

sure its use it can list you in the different yahoo country directories if you got the money and no worries that yahoo will reject your site go for it .
