Simple, you didn't have nearly 700 stickers to collect. :D Plus the packs of stickers were much much cheaper.. :D
Used to be about 20p a pack and you traded them at school with friends. Nowadays the stazi school teachers dont even allow that
Was tempted by this one, but still so expensive to complete. No idea how I managed to nearly complete these as a child
The code was only valid for the 1st 5000'ish customers. Just checked and the banner seems to be gone now so must be expired I'm afraid.
