Heron Foods is a retail chain which primarily sells frozen foods, opposed to fresh foods, and was founded in 1979. Over the years, they have opened a total of 243 stores and as of 2017, they are controlled by the discount giant B&M.
While their focus is frozen produce, they also sell bottles of juice, canned foods, cigarettes, vape related products, and confectionary.
One of the promotional programs which they run is the Saving Stamps Scheme. With this scheme, you simply pay ?1 for a stamp each time that you are in a Heron Foods store, and when you fill your card with 29 stamps you receive ?30 of credit to spend in store!
