lads....i'm not a big user of pellets myself,and i've no idea about their price really either!
last weekend at the nw carp society meeting,everyone who attended was given a 1k bag of csl pellets,these came from a firm called carpstream ltd,and they are located in the speke area of liverpool.
there is a website....
http://www.carpstream.co.uk
not much info really,just an email button for enquiries.
i can tell you that they are charging £25 for a 25 kilo sack of csl pellets (add p+p if your not collecting)
not sure wether thats a good price,but its a starting point for some of you i suppose.i can't comment on there effectiveness,as i say,i'm not a big pellet user....but i hope its a help
cheers mark
ps for those of you who prefer to phone them,the number is 0151-486-8866
