Montezuma’s brand manager Sarah Gainsborough said: “This arrangement is an opportunity for us to engage with as many people as we can on a scale bigger than we ever have before.”
Montezuma’s already has listings in Waitrose and at online retailer Ocado. Last year, it entered the US through a distribution deal with Trader Joe's.
The company was established in 2000 by Helen and Simon Pattinson from a single shop in Brighton, UK.
