The Cascade Mountain Tech Quick Lock Trekking Poles Andrew Skurka just reviewed look like a good replacement for the aluminum flick-locks from Walmart I've been using.

However, I have no Costco near me and I doubt those in the Midwest would carry them. I was hoping someone might ship me some for a small fee. It would still be cheaper than buying them direct. I may even get a few pairs for the family, which would definitely make it worth my while to find some kind soul. :)

PM if you'd be willing to help me out. Thank you.
