I buy and sell on the Auction. My seller alias is" curriesdaylilies". I have had good and bad experiences on the auction but you can have that anywhere. The thing that bothers me most is when people don't reply to emails or message and don't leave feedback. I had 4 auctions for seedlings that closed 2 weeks ago and still no payment. I am not going to relist. If they don't pay soon those pretty faulkner seedlings may end up on the compost pile because I need the room to line out some of mine. If people don't want to pay in a timely manner then don't bid.
One negative experience that became a positive experience happened to me on the auction a few years back. A woman bid on multiple daylilies I had listed. Within a few days of the auction closing her husband passed away so she emailed and asked if she could cancel without leaving her bad feedback. Well of course I was not going to do that to her at such a difficult time. The next spring she contacted via email and wanted to know if I still had enough of those daylilies to sell some to her and she even purchased again that fall.
