The price of buying school uniform each year can really add up, as kids can outgrow their clothes as quickly as you can get them.

But we've spotted an incredible offer that will save you some extra cash on the next school shop.

Thanks to an offer from TopCashback, Matalan shoppers who want to buy school uniform can get £15 off their bill, but only if they shop online.

The £15 cashback at Matalan deal can only be redeemed once per household, and is only available to new members of TopCashback with no previous purchases through the site.

As Matalan's school uniform is priced from only £1.50, you should be able to pick up some items for free. Sounds good to us.

The retailer stocks everything your child could possibly need, including unisex jumpers in various colours (from £3), backpacks (£2) and gorgeous gingham dresses for girls (from £6).

There's also an impressive shoe range with prices starting from just £3.50.

However, you'll need to be quick if you want to save £15 on your Matalan school shop, as TopCashback's offer is only available until September 6th. You'll also need to spend £15 or more to claim it.

Here are the simple steps you need to follow:

The deal is wholly funded by TopCashback, not Matalan.

Meanwhile, Tesco selling school uniform bundles with 100-day guarantee from £2.

Shoppers can browse the supermarket's entire school unifrom range on tesco.com and purchase from their nearest Tesco store.
