Craigslist. I have advertised plants and plant sales. You can put in pictures and prices and whatever explanation you please. You can put in your phone number so people can call and make an appointment to come by or you can have a specific day for a sale. How you word it is up to you.
You do have to figure out how to keep your ad close enough to the top of the list for people to see it. I always advertise when I'm going to be home to field calls and check your ad often as near the weekend it will disappear too far down the list for people to find it.
