Agree with Coddy And Mick, I make my own leads, rigs and other bits - i buy the terminal tackle of ebay for next to nowt - a 5oz gripper costs me about 13p to make.. and a rig costs about 30p. The only thing i buy is bait, as i don;t have the time to dig it. But i also buy bait from the supermarkets too.
And with micks statement - I have fished up the derwent too £24.00 for the day tickets, not guaranteed any fish - still got ya bait to buy and your fishing licsense.
The sport is expensive which ever way you look at it - to me its only the local tackle shops that make money especially the extortionate prices they charge for bait... I have fallen out with a couple just cause they try to take you eyes out. Their mark up must be massive..
