I go self catering in the UK every year and I always get basically the same shop delivered from Iceland on the first morning.
Nice breakfast things like lime marmalade, Greek yoghurt, malt bread. At least 1 full English, so 10 eggs. 2 pints of milk, hot chocolate sachets, French press coffee.
3 sandwich loaves and sliced ham, chicken, a huge block of cheese. Butter for bread and cooking.
Fruit and veg suitable for picnics or home.
As it’s Iceland they have loads of frozen choices and meat deals. I usually get a ready basted turkey breast, Findus chicken and fish steaks, lasagne, pizza, veg like broccoli and Brussels sprouts, oven chips and their amazing £1 strawberry cheesecake.
We go out for Fish and Chips one night and another to a fancy restaurant. This year we also did an Afternoon Tea which gave us leftovers for the following packed lunch.
With that delivery we might do one more shop in the week for fruit and veg.
I know there’s Ocado and other supermarket deliveries but Iceland takes PayPal whereas the others are difficult with non UK credit cards. They also give you £1 for every 20 you put in the App. It’s simple and there’s not a lot of choice. Toothpaste? Two types👍
I’ll see if I can get a screenshot.
