I’m not sure how true this is everywhere. Within walking distance (inner suburb of Dublin on the edge of the city center) I have two Tesco Superstores and about eight Tesco Expresses and Metros (Tesco splits its shop types into broad categories). The ‘superstores’ have the same pricing as each other and as suburban ones, the Expresses and Metros have the same pricing within each category, which is sometimes slightly higher than the Superstores. There’s also an Aldi and a Lidl; both are priced the same as any other Aldi or Lidl, as far as I can see.

If anything it’s more rural areas where you may see higher prices, in that your local ‘supermarket’ may be essentially a jumped-up chain convenience store.

The elevation in price is less location and more whether you're able to buy in bulk. With careful rotation discipline and a handcart it's achievable on foot though, although clearly more convenient with a car and a nice wide lot.

How heavy are your bulk purchases that you need a handcart? And how much do you save compared to just buying a kilogram of everything you ran out of this week?

For dry goods I don't even look at total price, I look at price per weight (wet goods, same but volume). It's almost always lower the more I buy. I'll buy the largest quantity I can consume before it spoils.

Off the cuff I'd say I save about 20%, and buy a few hundred pounds per trip. Probably saves us amongst a family in the vicinity of $1000/yr. This same concept extended to all other non-food consumables.
