I'm not sure if this is the correct place to post this...but, I have a question about my diatomaceous earth. I purchased a large 50lb bag, but I do not need that much. So, I listed it for sale on craigslist at $5 a pound, hoping to pay for my own as well as make a small profit. I have not had any interest. I was wondering if it is because I put too high of a price on it? Are there better place to advertise it? Thank in advance!
