You can always do both. Order the big heavy stuff online that keeps for ages (e.g. beans, rices, canned tomatoes, flour, sugar, spices) and go into the shop for a few extra perishable ingredients you need for a meal when you need them for a less stressful experience. This applies even more if you don't have a car. For balance, 90% of the item substitutions I've had have been fine (most stores in the UK email you the substitution list before delivery, and you can give substitutions back to the driver when they arrive) and the picked fruit + veg have been good for me too. I had a quick look, but is there any data on store food delivery being better for the environment? Wouldn't it save a lot of car trips if done properly?
