Kijiji is possibly the worst place for a business or professional to advertise their services or products. While the average Joe selling his couch without paying a dime to Kijiji has it easy, the advertiser, the one with the real money is left in the gutter.
I spent $300 in one sitting on promoting multiple ads on Kijiji. First of all, their category systems is a complete fiasco. Who doesn't have a Computer or Web category under Services in this day and age?! Second, I asked for help from their support. They deleted my ads and told me to post a banner.
Here's where the fun starts. Their banners on paper look very nice and promising, although they are "managed" by a second company, Shiny Ads. I never had a worse experience with an advertiser before! I am now waiting for the weekend to be over (apparently they don't work weekends...) and asking for a full refund; at the rate my banner is going now it comes down to about $11/click (!).
In other words, stay back if you are a business. They will squeeze every penny from you and give you close to nothing in return. If you are simply a consumer, then by all means, go and sell your couch!
