I was in B&Q and came accross this shed on clearance at £199.99 down from £399.99 which I thought was a pretty good deal. However it went through the checkout at £100!!
I think it is instore only as I cant find it online but here is a link to the product on the Keter website.http://www.keter.com/products/gemini-6x6/
I know the staff usually pick these up for themselves but they didnt seem to know about the reduction so you may get lucky.
