The prices of the play pools are starting to drop nicely now, and this looks like an awful lot of fun for your money. The Chad Valley Activity Pool Play Centre has a third off at Argos, down from £29.99 to just £19.99.
This is a paddling pool with tons of extras to keep the kids entertained in the sun. There's two little pools with a slide in the middle, plus a slope to send play balls down and watch them splashing into the water. There's also a flower that turns into a water sprinkler when you attach your garden hose.
This looks great for younger kids as it's not too deep, and reviewers have said that it works well as a ball pit too.
There's plenty of stock about for free reserve and collect from Argos stores, or home delivery costs £3.95.
