Yes! Bigger family here and it helps to spread out the labour through the week. Better for fridge space and visibility of ingredients in our compact kitchen.
We do either Sun/Mon and then Thurs/Fri depending on activities. Definitely waste less food, and less midweek packed lunch panic.
DH and I split the cooking week in half, so one of us is responsible ordering for one of the shops each. This requires good stock checking before ordering, but otherwise works fine.
Tesco delivery pass here, and just treated ourselves with an upgrade to anytime. Will be nice to have the option of same day for particularly busy weeks.
