You have partially described Cook, in the UK https://www.cookfood.net/ https://www.cookfood.net/ They only sell ready meals, aiming to be a higher quality than the slops you can buy in supermarkets. They've won several Great Taste awards here, which is a fairly well-respected stamp of approval. Perhap the main difference from what you're suggesting is that they're not ingredient kits, they're prepared meals or components (e.g. main/side/dessert). They have high street shops in - let's be honest - rich parts of the country like the South East. Quality seems quite good and the price isn't that bad - at most £5 per person with reasonable break points for couples, families. The store itself is a few rows of freezers. I've never tried, but people I know say that it's good if you need an emergency meal that actually tastes nice.
