REI in Brookfield has their 1/8" shock cord on sale for $.03/ft and 1/4" shock cord is also on huge sale but can't remember price. I bought a 100' of 1/4". Needed about 20' right now and the rest will get used up in other small projects. While I was checking out there was a pre-packaged 7' brand name length of shock cord on a kiosk for $4.50. Made me laugh holding the 100' for $3.
