Here's a handy little bargain for you. Mothercare have this Spotty Changing Mat at half price, down from £6.99 to £3.49.
It come in a pink or neutral cream colour that they are calling 'biscuit', both with white polka dots. There was a blue one but it is sold out now. All are on the same link, you just need to tick the box on the page to select your colour.
Both colours seem to have plenty of stock in right now, and are available for free click and collect from store.
There's not a lot else to say about a changing mat is there? But it's a good price if you need one!
