This is my first post so please be gentle. Just been to my local JJB store (Glenrothes) and they had Celtic away tops from the 06/07 season for 50p. Although a bit out of date for 50p you can't complain!
Had the top in sizes large and x-large.
They dont have any left online, but worth a look if your close to a jjb!
Also if you have a valid ucas card you can get 10% off this price, so you'd get it for 45p :)
