It is the first work to emerge from the agency since it won the account in May following a five-way pitch.
The TV, radio and press work breaks this week and will run until Christmas.
It aims to convey the range of products available at Poundstretcher and the value it offers.
In one of six 20-second TV spots, the scene opens with a man sitting on a door step. He looks up to see a Mini Metro struggling down the road weighed down by an enormous tree tied to its roof rack.
A voiceover says: "With packs of six baubles for only £2 and three packs for just £4 you can afford to have a bigger tree this Christmas." The endline is: "Poundstretcher. Making Christmas better than ever."
Media planning and buying is by Brilliant Media.
The radio ads will be aired regionally with a northern bias, while the press executions will appear in a range of national newspapers.
Rupert Jones directed the films through Serious Pictures. They were art directed by Dave Beverley and written by Rob Burleigh.
