Beauty brand Benefit has linked with Diet Coke to add glamour to soft drinks.

Rolling out this week across the trade, the limited-edition Get Glam Diet Coke packs feature on-pack codes that consumers can use to access £5 vouchers to spend at the Benefit online store on their next purchase of £20 or more.

The activity follows several other beauty and fashion tie-ins for Diet Coke, including the Nails Inc promotion it ran last year through Boots.
