I know this is an older post but if anyones interested I found a shop in USA a few months back that sent me about 400 to 500 ft of 550 paracord for about US$8 shipping. The whole order (with a few whistles/key ring bits) was about US$70 and took about 2 weeks from memory .
Anyone interested let me know and I'll try and track the shops info.
OK Found the info
Site is SOSAK- Its a bit dated but works OK - with Credit card or ebay. the guy Tom seems a decent bloke. I got some black and OD plus some orange for an emergency kit. Tom says its all 550 type 3 paracord. It Looks legit with 7 twisted internal cores
BTW - Some Bunnings stores do nylon cord that looks similar which may be OK too- Its called venetian blind cord - I call it man-cord else the wife will give me stick over buying girly cord! A few sizes - The black 1mm size is OK for repairs and binding and fits a big darning needle for canvas repairs.
I sympathize with John above. I too had a big roll I acquired while I was in. Took it for granted - expected it would be easy to get hold once I was out - until it was gone. Now I have to pay for it - damn
Hope this helps people
