I spotted this in the bargain aisle in our local Tesco Home Plus today. The SEL said reduced from £69.97 which is the RRP, but has been reduced most places to about £30 now. I think it's just an expensive Wendy House but not so bad at 17 quid.
I know Tesco don't have the same deals in all stores so I would call if you are making a trip just for this. It's usually hit and miss in there and unfortunately I usually miss.
This is discontinued online at Tesco Direct so an in store deal only.
