Interesting the number of 'hits' you get when you plug in 'artic fox + fly' etc. Pricing is quite different ranging from $3 -$5 per packet (don't know for sure if they're of equal size) and a considerable number of colours. Willie Gunn put me on to a UK site but after repeated attempts no luck in getting the site to load. Want to go back and explore this one tho, gather it's one of the largest suppliers in the UK.
Now I know this is going to cost me money.
