   Throughout the promotion and at the Promoters discretion, letters will be given away at random through online, television and print forms of media. To redeem these letters participants will need to either take a photo of the letter and upload the photograph to the ‘image section’ of their dashboard on the promotional website in order to register and use the random letter, alternatively if the participants are unable to upload a photograph of the random letter they may enter the unique code as found next to the random letter onto their dashboard on the promotional website in order to register and redeem the letter. Participants may only use one method to redeem each random letter.
9. Swapping letters
   1. Entrants can start the swap process by selecting a letter that they want to swap out of their collection.
   2. Entrants will be able to participate in up to 5 letter swaps during the Promotion Period – this includes both ‘random swaps’ and ‘swaps with friends’:
      1. Random swaps: Once an entrant has selected ‘Random’ they are then asked to confirm the swap. Once confirmed their chosen letter disappears and a new letter is selected at random from a ‘pool’ of letters that are stored in a database and the letter is put into their Dashboard. This swap is instant and all letters are treated equally.
      2. Swaps with friends: When an entrant chooses to ‘swap with friends’ they can determine what letter they want to receive in return. The system will generate a unique URL that the entrant can share or pass to a specific person via Twitter, Facebook, Whatsapp or email. When the friend clicks the link received they are prompted to log in and the system will check if they have the letter that is on offer, if they don’t they will be presented with an error message. If they do they will be asked to confirm the swap, once confirmed they will receive the letter. The entrant that initiated the swap will receive an email telling them the swap has been completed. Both the initiator and the receiver of the letters will be deducted a swap. Once the swap has been completed the link will be ‘dead’ and anyone clicking the link will be guided to an error message then back to their dashboard.
   3. An entrant can view their swap history at any time during the Promotion Period. If an entrant has outstanding ‘Swaps with friends’ they can choose to re-request the swap or cancel them. If the swap is cancelled the entrant will have that letter added back into their dashboard.

i just entered my first code from a packet of promotional crisps and got the following message;

Sorry, this code has already been used. Please try again are the codes not individual?

Just watched the TV advert with Gary Linekar and it says there is a hidden bonus letter somewhere in the advert. I rewound the advert, but still didn't spot it. Does anyone know where and what it is?

How are the letters assigned? Does each code have a particular letter already assigned to it or is it just a random number each time?
