Sorry to say I can't recommend dealing them. My experience with "yellowpages.ca" has been a nightmare. I signed up for a 1 year deal with mts (Manitoba Telephone System) yellow pages phone book and also took an online ad with "yellowpages.ca" My whole year has been, I got no invoices for 3 months, then I get collection calls for the outstanding amount. I argue that I never got ANY invoices. They sent invoices by email and I pay them. Then I get no Invoices for 3 months and more collection calls. Again I tell I got no Invoices to pay. Then email me the invoices and I pay them. THIS CYCLE continued for the WHOLE YEAR! Add to that the return on the advertising was diminished by mistakes they make on my online ad. The proof I okayed was fine, but what they put up had the wrong address for almost four months. (yes I know I should have checked but I trusted that if the proof was right the ad would be done right as well.) I would take an ad in the phone book again. BUT never with "yellowpages.ca" they seemed like they had very low traffic and counted impressions (not unique visitors) to hype the stats.
