Bill, sorry mate, caps were mainly given to contributors to FISHINGmagic, or to people who attended certain fish-ins. And right now we don't have any in stock anyway!
I remember trying to buy a shop display Duracell rabbit at Schipol. I'd had a bit to drink so I offered this shopkeeper the equivalent of Graham's bait bill for a decade. Didn't work though, the rabbit stayed Dutch. Nothing to do with FM caps but it shows the demand is often there for items difficult to get.
Grahams bait bill for a decade? You cheapscate, no wonder you didn't get it. Graham bums all his bait, so a pint or two of maggots don't come to a lot over a decade.
