Superdrug is giving online shoppers £10 off their shop when they spend £40 or more.
The discounts are automatically applied at checkout online at www.superdrug.com and include purchases of products across all categories including perfume and make up.
Eagle-eye shoppers spotted the deal being added to their basket online and have been sharing the promotion with others on deal-sharing forum Hotukdeals.com .
Several posters used the deal against other offers, including 3 for 2, and the automatic £10 savings was applied every time.
One member did add, "Don’t think this is intentional so may be pulled at some point", so customers eager to give this a try on their own order may not be as lucky.
However we have tried this morning and the discount was automatically included, so strike while the iron is hot if you're after some pricier items.
The chain has a number of other great value offers, shoppers can take advantage of including half price Nip + Fab make up , 25% off Burt's Bees baby products and half price Braun electricals .
If you're planning to do a big shop it is also worth signing up for a Health & Beautycard to earn points on your shop and get access to exclusive perks and discounts. Customers can register for a reward card online by visiting www.superdrug.com/beautycard and will be instantly able to start earning points.
