Sainsburys expanding

Spotted in this week's Advertiser Sainsburys have put in to expand the store at Straiton and (can't remember the exact terminology but...) create a raised parking area.

They also plan to relocate the petrol station so it looks like we shall have one massive store when they are finished (won't make the other supermarkets very happy).
It seems like they have given up on the proposed store at Dalkeith since First Bus have done nothing about moving elsewhere.
