A new flavour of Prime called 'X' is set to launch in Aldi stores today (Wednesday, June 5) alongside a competition with a $1 million prize.

Prime Hydration already comes in a variety of different flavours in the UK including Lemon Lime, Meta Moon, Ice Pop and Tropical Punch.

Other more recent flavours include Cherry Freeze, which launched in January, and Strawberry Banana which came out in April.

This new limited-edition flavour also has a competition element to it, as customers could potentially win a $1 million prize by completing a certain task.

Those who want to win the $1 million prize will need to try and collect 12 bottles with unique barcodes.

This will create a map which will lead them to where the money is being held.

In a statement, Aldi said: "The NEW Prime X flavour line offers fans the chance to embark on an interactive ‘hydrohunt’ challenge.

"This epic expedition encourages shoppers to collect 12 bottles with unique barcodes to build an in-app map.

They continued: "Priced at just £1.99 (500ml), the highly-anticipated drink will be available as a Specialbuy, and as with all Specialbuys, once they’re gone, they’re gone!"
