I remember those shirts Fuct used to do with stuff like 'It's too late to recycle' and 'Fight crime, buy a gun' on them from when I was about 15/16.
In a pre-internet age I had to go up to Slam City Skates in Covent Garden to find any sort of range.
This was back when there were only 25 or so decent skate shops in the whole country. The nearest shop to me was Off-Beat in Basingstoke, it was about half the size of my bedroom and used to have about 20 tee shirts, 5 hoodies/sweatshirts, 4 varieties of Etnies or Duffs (this was when Duffs were making amazing skate shoes, anyone remember the Strombolie?) and about 15 decks plus hardware in at any given point. That was pretty much it, you'd end up buying whatever they had rather than what you actually wanted.
There was always the option of ordering through mailorder set-ups like Rollersnakes and HSC though.
