Cindy - The one time I did have someone complain I offered the buyer his money back, or some other seeds since I was out of the ones he bought. The buyer didn't take me up on either. He said he just wanted me to know what happened. I always worried about the listings that went for higher prices. When someone pays a lot for seeds and they don't germinate, I think they get pretty upset. I would offer the complainers some replacement seeds. I know I have more seeds than I could ever plant or sell. It's a small gesture that could make someone a loyal buyer for life.
