This is the cheapest I have ever found...unless you get some for free that is.
Yet I never have seen this in Camouflage before.
For anyone needing a ground cloth or tarp or for whatever.
Here is the link, the man is trustworthy and sells it on eBay for only .99 cents a foot and only $5.00 flat rate for shipping.
You can buy up to 50 feet if you need it.
