The promotion is designed to encourage trial and coincides with the introduction of fictional awards on packs of apple and orange flavours .
Orange features an accolade from the
League of Ecstatic Tongues , while apple's imagin ary prize comes from the
Newton Academy of Apple Worshippers .
To get their money back, consumers have to write to Britvic to tell them why they weren't satisfied and include the
awards artwork from the pack.
Head of carbonates Peter Kirby said: "The promotion sits well with Tango's irreverent personality."
