How much do you see them going for?
A friend became seriously ill about two years ago, sold their house and moved in with a family member. After checking storage prices a relative bought two containers, placed them on their farm and stored all the friend's stuff, furniture, garden equipment etc. These had been used once, shipped from China and then sold on, under £5000 for both of them.
I was surprised at how good they were. Well sealed, water-proof, mouse-proof, secure and well painted. I'm occasionally asked to fetch them something from the container, and they still look very good, with no signs of corrosion.
I've no idea if prices have gone up, down or stayed the same since the pandemic, but at the time I was surprised at how readily available, cheap and well made they were. All we had to do was find the right person to ask.
