Well, we'll have to agree to disagree. I've lived in Coulsdon most my life and it's starting to change massively, just like Purley before it. Stores like Tescos and opening hours such as they bring diminish a small town like Coulsdon. Waitrose isn't much more expensive at all, pretty much a fallicy. And nuts opening hours?? 8.30 till 20.00 most days seems fine to me. If you want to shop so late then toodle off down to Purley. Simply put those type of opening hours and shops don't work in small towns. They change a small quiet town into a large noisy one thereby destroying what once made it so nice.
You're right, we'll have to disagree. With Purely down the road and the one at Caterham the only people I see shopping at the little one in Coulsdon are those that live in Coulsdon and Hooley which means more choice and convenience for the locals. For me living in Hooley its a boon since all we seem to have are a vacant cafe, a pink furniture shop, a clock repair and barometer shop, 2 petrol stations, a newsagents, and I think a castle door shop.
Not having to go all the way to Purley means that Coulsdon gets more of my money which also includes the shops around it which I and I'm sure others use also (The Jewellers, Indian, Chinese, Italian, Hardware and Boots mostly).
I could understand if they had built a large one but its tiny and doesn't even have a car park. Waitrose is larger and has a wider selection AND a car park. All the tescos offers is another option and better hours.
