Wandered through the local Basspro here in OKC this afternoon for a few minutes and there was a large display right up front near the registers with LifeStraws for $19.99. Not a bad deal IMO.
If there is one in your area, it may be worth swinging by and picking one up in you are looking for something like this to add to your kit.
