I've been thinking we should get a wheelie bin for taking bin bags down to the main bins (and potentially storing them short-term). They're actually not so expensive as I thought and you can get them on eBay:
Might be worth paying the extra £1 not to have a logo on it (and grey probably better colour than green for refuse).
Sounds like a great plan, and a much better look than the bags hanging around.
We have a wheelie bin now.
