I've just done the years second "big shop".
I can't do my normal shop using the bike trailer, and what I can sensibly carry back from Sainsburys is inly enough for day to day stuff. I needed some heavy things, or just lots of some smaller stuff, so I decided it was time to get the car out.
Generally it's a bit silly to use a car to go to Sainsburys, since it's about 3/4 mile away, but if I can make it worth it, I'll use it, and I can't really do even a moderate shop on foot at the mo.
I did manage to entirely fill the boot up, about a dozen of mostly the large reusable shopping bags, an the kitchen is still partially filled with shopping, much to Talisker's annoyance!
