Found these in my local store (Basildon) today, set of 4 good quality storage boxes with lids, largest box is about 37cm squared (or should that be cubed...I am never sure!), smallest about 22cm.
They are a kind of small basket weave finish and seem to be fairly well made. They also had other storage boxes reduced by similar amounts, some in the same range and other wicker style ones too. I did find a smaller set online but the reductions weren't as good so seems to be instore only.
Please not image only shows a set of 2 smaller boxes, could not find a pic online
