Wow. This looks like the most amazing fun for the garden, and it's a fantastic price as well. The Airpro Bouncy Castle with Slide and Pool is reduced from £130 to £90 at Tesco Direct, and you get free home delivery as well.
The bouncy castle part comes with a built-in fan that can be turned off once it's inflated to keep the noise down, and you can use the castle on it's own or add the extra parts when you want to.
The slide leads down into an inflatable pool that can be used either for water outside when its nice and warm or for play balls.
All toys over £10 have free home delivery from Tesco Direct at the moment so that saves you the £3 charge, or you can click and collect if you prefer, though I would think that this is going to be a pretty bulky item.
