If you can shop in the 'normal' shopping hours, Marple is a very good place to pick up everything - certainly the quality is far higher than any supermarket.
I'm afraid that for sheer laziness, the supermarkets have the edge if, like me, you don't get home until 8pm, I can;t really expect Archers to open on the off chance I fancy a loaf.
I suspect that over time (ie 10-15 years) "normal" shopping hours will gradually become something like 10am-8pm, or even 12pm-10pm, as our retailers catch up with how the rest of society operates.
Gosh, how DID we cope in the days when no shops were open 24 hours a day, local MUDC byelaws prevented certain businesses from trading on Mondays and there was universal obligatory half day closing? It's a wonder we didn't starve to death or have to go barefoot and in rags for want of shop keepers prepared to work all hours god sent in case someone needed a loaf of bread or a pair of socks in the middle of the night.
What happened to your ability to organise your life? Working women have done it for eons. We shop in our lunch hour or on Saturdays or whenever our day off falls. I'm sick to the back teeth of this constant whining because everyone is out of step except you. Get a life and accept the shopkeepers' need for one too.
We coped because generally only one parent worked full time, the other parent either didn't work, or worked part time. Until not that long ago (relatively speaking) it was quite rare for both parents to be working full time. And single parent families (which were also rarer "back then") often lived with extended family, of which not all the adults would be working full time.
Society has changed massively - for better or worse, take your pick, but it has changed - and some people (and businesses) are still struggling to realise this.
However nor doI expect them to be closing at 5.30 just as the great mass of people are getting home nor do I expect people like Archers to be almost out of stock by 3pm.
Marple retailers have had it easier than many, because the aging population has shielded them from this change to a degree, but as they start moving on, and get replaced by younger families, they'll have to adapt or die.
