The more I think about it, the answer to that is no. From what Webtrekker says, it sounds like a good shop but if they deliver in the Bedlington area then it's already 'on your doorstep', so to speak. My money would be on another supermarket along the lines of Lidl. Waitrose, Tesco or similar. A bit of competition is great for keeping prices down.
Of course, we all have different views on how, when and where to shop. it has to fit in with everything else that's involved in running a household, holding down a job and raising a family. It's a very personal choice. Whichever way it goes some will be happy and some will not. It'll be interesting to see what happens.
