Interesting offer here from Puma. Go to a Puma shop, or Schu, USC or Footasylum in Manchester and pick up a Puma City Card for free. This then gives you 10% off at the given stores on Puma products until 28/06/08, furthermore if you register at http://www.pumamanchester.com
you get a big list of restaurants and bars in Manchester where you get quality discounts such as 20% of the bill, 2-4-1, 30% off Haircuts and other such stuff not to mention student price tickets at AMC Cinemas. Very good in my opinion even if only for just under one month.
As mentioned unfortunately only for Manchester, AS FAR AS IM AWARE. May also run in other cities.
