Large Disney and Paw Patrol storage bags ( L:58cm W: 30cm H:48cm) for £1.99 in Home Bargains Cannock town centre store. They had Disney Princesses, Mickey Mouse, Minnie Mouse, Paw Patrol and the assistant said there is also an Avengers pattern. I have these in plain patterns (usually £1.79) and use them for storing clothes, toys etc. They're great for storing stuff in the loft as well. Jojo Maman Bebe sells the same size bags for £6.00 and similar styles on Amazon are £2.95 plus postage from what I can see. Photo below of the princess bag showing the size details.
