I recently changed my method of supermarket shopping and it has mad it so much more enjoyable, as well as saving me a lot of money.
I now do an online Tesco shop every other week for all my "bulk" non-food items like laundry powder, nappies, wipes, toilet roll, bottles and cartons of soft drink, etc.
(So so easy using the iPad/iPhone app, for anyone who hasn't tried it - takes me 5-10 minutes.)
I then pop to our local Waitrose (a 2-minute drive) once a week for food, and can spend my time browsing and planning meals properly for 30-40 minutes. I'm not a big foodie, but DH is. DH also pops along at the weekend to buy the odd item.
Beforehand I was going to Tesco once a week for everything and it drove me insane. The staff were so rude and they always seemed to not have what I wanted, plus I usually spent a lot more on things we didn't need.
Am currently pregnant with DC2, which is what prompted the change in strategy, didn't want to lug heavy stuff to the car.
