McColl's is one of Britain's biggest convenience store chains in the UK who have over 1,650 locations nationwide, one-third of which have an in-house post office. Up until a few years ago, the majority of the McColl's locations were in Scotland.
Their product line contains a lot of generic products which are expected of a convenience store. Cleaning products, general groceries, toiletries, and meat - products which you'd expect to find. Some of their stores have fresh baked goods sections while some of the others have a butcher.
One of the most popular reasons for customers dropping into a McColl's store is to get a newspaper in the morning, along with some fresh milk.
