Tesco is selling the Out There 12Ft Quick Up Pool which strikes me as a really good price for a swimming pool of that size. I've been browsing around Amazon and the next best price for a 12ft pool is upwards of £80 . There's free next day click and collect from Tesco on this item, and standard delivery is £3.
If you're not sure about the money saving possibilities with this pool, just take your kids to the local swimming pool for an afternoon. It costs our family of four almost £20 for a 3-hour pool side session, not including the ice creams my girls seem to be able to spot from across a tidal pool!
This large round pool has an inflatable 3-layer laminated PVC wall for longer lasting durability and includes a filter pump as well as a ground cover to help keep the water clean. When you have finished using the pool you can drain it by connecting a garden hose to the drain valve on the side of the pool.
Sounds good to me!
