Argos have reduced the price of these super cute kids pyjamas down from £5.99 to only £3.99 a pair! There are two designs, Peppa Pig or Thomas and Friends available at this price.
Both pairs of pyjamas are long legs with short sleeved tops, and are available in sizes between 18 months and 5 years. They are made of 100% cotton and are machine washable.
The links above will take you to the 18 month size, but each size has a different item number so you need to use the drop down box to select the size you need before ordering.
Both Peppa and Thomas PJs have stock everywhere I have looked, and you can reserve and collect them for free, or home delivery is from £3.99.
