No idea if i'm allowed to link to other website that sell stuff but I know a lot of us have kids that aren't dry at night and the underjam nappies are so expensive.
hotukdeals.com has a reference on the main page to a deal amazon is doing, 4 packs for around £11 which is a great deal compared to normal shop prices, here's the link and hope it helps some of you, we can all use cheaper nappies that's for sure!
