It's time to get some diatomaceous earth for my girls as well as a little for my bug-ridden chard. I can't seem to get the food grade in my city, so looked on ebay. Has anyone ever bought from this seller? s/he has 100% approval rating however ONLY accepts PO or Western Union money orders. That makes me nervous because there's no way to complain if there's a problem except via ebay. http://cgi.ebay.com/5-lbs-Diatomace...ryZ46532QQssPageNameZWDVWQQrdZ1QQcmdZViewItem Thoughts?
