As for the website website groups, I tried Natural Magic because I thought it would be a good fit for a Druid, but the coven was practically stagnant.
As for real life groups, I'm a member of ADF: Ar nDraiocht Fein, A Druid Fellowship. The annual membership fee to ADF as a whole is only $25 if I remember correctly. You then have access to their dedicant path material and a mentor free of charge after that. They also have listing of the local Groves in your area, and it was really easy for me to find mine. My mentor is lovely. Their high day rituals are open to the public, so you can attend a ritual in your area to see if it's something you'd like to get into before you pay for anything. The people in my local Grove are super friendly, and so accepting and ready to answer all my Druidry questions as well as include me in their rituals. I recommend looking them up and meeting your local Grove.
