I used to trade Wackys in the very early years, but then we started moving around too much, and I lost my trading partners. But, I recall one trade for the last Series 2 sticker I needed, Run Tony. I traded my extra Liptorn for that. And later on, I did an early email trade, my extra Cheapios poster that I used to have very neatly pinned to my bulletin board for a set of punched die cuts, with reproductions of Ratz and Cracked Animals. I didn't have any die cuts at that point.
