I found the offer mentioned on hotukdeals. The link is A Free £50 Bet From Paddy Power for Torres & Carroll jerseys! but I don't know how you get there.

Got a "Torres" or "Carroll" adult football top? We’ll give you a £50 bet for it – and send it on to someone who really needs it!

It's really simple. All you have to do is:
1. Send your shirt to Paddy Power Silver Lining, Unit 4, Capel Close, Fairwood Industrial Park, Leacon Road, Ashford, Kent, TN23 4GY
2. Include a short note with your NAME, PHONE NUMBER, email address (if you have one) and Paddy Power Username. (If you don’t have a Paddy Power account – open one at Online Betting from Paddy Power | iPhone & iPad Betting Apps available., it’s easy.)

- Shirts must be received by the 1st of March
- All shirts must be ADULT sizes with Carroll or Torres plus relevant number on the back

We'll do the rest, and let you know when your free bet has been credited to your account! All the shirts collected will be distributed to those who need them around the world.

- Please remember to be careful to give us your exact username.
- Over 18s only!.
- One official replica adult shirt per household.
- Free bet stake is not returned in winnings.
