I would agree with everything Paula said. My own personal reason for starting to sell was to thin them out. After giving away a lot to friends and relatives, who no longer wanted any more, I had to start selling them. I don't make much money either. Seems like the expensive ones don't increase like the older ones do and people are looking for the newer ones more than older ones. I actually do better selling seeds. I am a small back yard grower so I can't sell from my home. Only internet sales. I package mine the same as Paula does. Shipping prices are difficult because all plants do not weigh the same. Shipping is based on distance so within my state I charge less than I would shipping to Florida or Texas. I have also lost money on postage several times by not guestimating enough. It is a wonderful hobby though and I enjoy it very much. My garden inspector said don't ship to western states because they have a lot of regulations. I don't ship to AK and HI or course, but also don't ship to WA, OR, CA, AZ or NM. On deciding on the prices, I get tons of daylily catalogs. I go through them and see what others are charging and I always try to set mine at competitive prices. Also, I keep in mind that with each passing year, one must lower the prices as the daylilies get older. I certainly wouldn't charge a high price for a plant hybridized in the 80's. Because I am such a small business, I do not advertise but I do have business cards and on occasion have handed them out to people I run into when I am shopping if the conversation warrants it. I also have taken plants to our annual perennial exchange and that gets me some exposure. Now that my city started a farmer's market, I may actually take some there next summer.
