Former Co-op store in Dalkeith

Snapped this in passing - some nice old buildings left in Dalkeith, often overlooked and taken for granted (but a lot have been demolished and developed, I hear). This was the SCWS (Co-Op) general store, from the era when they had these big stores in most towns in Scotland - and several in the cities. I don't remember this being used by them since I came to Dalkeith, but I remember their store in Lerwick, and at least one big store in Edinburgh (now the Point Hotel). Something tells me there was another near it, off Lauriston, but maybe that wasn't a Co-Op store.
