I'd be happy to periodically check Canadian Tire. It seems strange though, as us Canadians love our cars. We like to use our favourite soaps, such as Auto Glym, Meguars and so on. We also know how to get the soap into our sponges, rather than rely on a company to do that for us.
Anyway, I'll report if I see them there.
I don't see the Auto Sponge enjoying much longevity up here in a time where much of our municipalities are moving forward to ban the sale of bottled water in many places in order to reduce waste. All of our major cities are erecting public water fountains in public places.
A sponge that is useless after 8 uses might come under similar scrutiny, or perhaps not. Most of the garbage from British Columbia is sent to landfills in Washington.
