Need some old style help with storage boxes

ti1980

I know a lot of you watched Anthea Turners programme when it was on a while back. I watched one episode when she was helping someone and she was going on about storage boxes that could be put on top of wardrobes etc.

I thought it was a great idea at the time but whenever I have seen any I have always thought they were really expensive for what they were, a bit of plastic!

I could really do with a couple now though, have seen them for sale at Sainsburys for £12.99, apparantly they are a 'special purchase.' Is that a good price or a rip off? Have any of you seen any or bought any recently?
I should be going shopping today (friend of mine with a card is helping me out) so would be grateful if you know anywhere I can go to get them.

Thanks in advance.
