Next time round, I forgot to place my order until fairly late in the day when I realised we were almost out of bread and milk, but luckily you can order right up until 9pm for next day delivery - which meant we had bread for the kids lunchboxes by the very next morning. This can be really handy when you run out of something crucial!
I also like the fact that you can order some of the heavier items that you might not want to carry home from the shops. We go through a huge amount of milk, potatoes and squash, but as I only have the pushchair during the week, and no access to a car, it can be really hard to fit everything I need into the basket - and if it won't fit it means I have to hang the bags from my arms while walking home. Not fun.
We have now had 4 deliveries from milk&more, and have not had any major issues. There was one delivery where the milkman forgot to leave one of the items I had ordered, but by 9.30am he had popped back and dropped it off for me. No big deal, and actually a very good service. I can highly recommend it.
