What? Monoprix is your regular supermarket.
Although unlike in the US, most of its competitors are owned by the same parent company, Casino Group.
They print little puns on the packaging of their own products.
The bad accent of the man doing the narration is a little unnerving; they could have gone with a heavy French accent which could have been funny (maybe), or they could have hired a native speaker. But this sounds like they took the first guy in the hall who said he spoke English.
Monoprix is the most expensive supermarket.
