Asda are currently selling Huggies 'Little Swimmers' swimming nappies for £3 per pack - they usually cost between £5 - £6 a pack in most places. All 3 sizes are on the deal (Small - 12 in pack , Medium - 11 in pack , Large - 10 in pack [I think] ). Not too sure how long it's on for, or if it's online too. Works out 25p per swim nappy (on the small size) - a lot less than you would pay for single ones at the leisure centre.
