Co-Op
From Tardis Wiki, the free Doctor Who reference
Jones the milkman drove a Co-Op brand milk truck, delivering milk regularly to Global Chemicals. The Third Doctor borrowed this milk truck and disguised himself as Jones's elderly father, substituting for his supposedly ill son, in order to gain entrance to the facility. (TV: The Green Death)
There was a Co-Op in Radyr. (AUDIO: Broken) Concerning the fridge in the TARDIS, Evelyn Smythe asked the Sixth Doctor if the fridge restocked itself or if he visited a Co-Op without her knowledge. (AUDIO: Project: Lazarus)
