This is a competition from Brown Bag Crisps Login To Enter »

FREE CRISPS! We are feeling extra jolly today, so are giving away a box of crisps. Just because we can. Oh, and it might help us get to 10k followers! Just follow us & RT this to enter. If we get to 10k, we'll give a couple of boxes to the lovely @daisy_haggard too! #competition

Sometimes promoters tweet more than once.
Tweets will only get updated when you re-fetch them. This helps you because competitions will no longer "jump" between pages when competitions get added or competitions finish while you are browsing them. Competitions get "fetched" when you login or manually re-fetch them with "Forget Ended Competitions & Fetch New Ones". Additionally hidden tweets will stay visible until you "fetch" to save reloading the page and save you from losing your position.
