I thought Waitrose had their sights on Teigmouth.
And how do you know they wouldn't get any brown envelopes from Lidl or Aldi?
Totally agree with you Anon. Can I also point out that comparing Dawlish shops with those in Teignmouth is also a nonsense as Teignmouth has many more shops than Dawlish. Dawlish town centre is basically 1.The Strand. 2.Brunswick Place and 3.Queen Street. Because Teignmouth has shops Dawlish hasn't it will of course draw trade away from Dawlish eg New Look, Peacocks, Specsavers, W H Smith, ...
But the co-op in Teignmouth (both of 'em!) are actually in the town - not out of it. Out of town/edge of town stores do not necessarily bring people into town centres. I suspect ASDA in N.Abbot easily does more to bring people into the town than Sainsburys or Tescos put together.
Anon - you presuppose that when people go to a supermarket to shop they then go to the town to ....er......shop! That ain't necessarily so. Hands up all those who shop at Tesco in Kingsteignton and then go into Newton Abbot?
