Sainsbury's has launched a £1 sale on school uniform, with pinafore dresses, skirts and boys' shorts for a fraction of the normal price.
Bargain hunters have spotted huge reductions in stores across the country, including pleated dresses for £1 instead of £9, making a saving of £8.
The dresses, sold under the TU brand, come in a pack of two, meaning that you're actually paying just 50p per item.
The label explains that the dresses are easy to iron and come in a fabric that repels water, meaning they're less likely to end up stained.
Sainsbury's said that the deal is now live nationwide, but only while stocks last, and numbers are already low.
If your nearest store doesn't have any in stock, it means they've sold out.
The deal isn't available online either, it's only in store.
The price cut was spotted by a mum in a London branch of Sainsbury's, who then posted it in the Extreme Couponing and Bargains Facebook group.
She wrote: "Girls pinafore dresses for £1 in Sainsbury's. I assume it's last years design as there were different ones on the rack."
Another mum said she found a similar discount in a different branch - but for other items.
She commented: "I got pinafores and skirts in ours (Epsom, Surrey) yesterday all £1 for 2."
It's not just girls clothes as another shopper said she found some for boys' clothes too.
She posted in the group: "I got 2 pack wee boys shorts for £1."
Sainsbury's isn't the only supermarket offering the massive discount on its school clothes.
