Maybe they are an outdated idea but plenty like a bargain.
The pound shops have taken over in this area and maybe the stall rentals?
I used to shop around the market in Town most weekends, these days, apart from fruit and veg I don't buy anything.
Spreading the market around town isn't I don't think helpful - it would look so much better if they were all brought back into the square and maybe more inviting for people to shop?
I stayed over night in Sheffield a couple of years ago and they had a street Market with the stalls adorned with Christmas Lights and Father Christmas in his Grotto.
A lovely tourist attraction and atmosphere.
