You may simply want to call around to your local greenhouse or florist locations. You'd be surprised at the selection that many small operations carry. Here is a mail order company that sells a 2-3 year old Meyer Lemon or run a search on www.dogpile.com and punch in "Meyer Lemon", you'll find a slew of sources yourself. Best of luck!

When we went to Florida in January I picked some lemons from my friends tree & brought them home with me. Squeezed the juice into ice cube tray & froze them to use in the future. Peeled the outer skin off the seeds & planted them in peat pellets. I kept the pellets in a domed container that you would get take out food in. It acts like a little green house. I have 14 little lemon trees started right now. Try it.
