There's a variety of pop up room tidy- slash - laundry baskets available from Asda for half price. They are normally £5 but have been reduced to £2.50 and with click and collect you don't pay delivery.
These pop up room tidies are really handy both in use and in storage. They are meant to be for tidying rooms, but make great laundry baskets and can really be used for anything, including hiding toys when guests arrive!
There are three for £2.50 - Toy Story, Spongebob Squarepants and a camo one. There's also a pink option for £3, and then another three that are still £5.
There's pretty annoyingly absolutely no information on the website as to size, materials or care instructions, but it would be hard to go wrong with these anyway.
