Best way to advertise for free

Tweet

So since Im starting to feel a little better and we've settled into our new place and have everything up and running again. Im wanting very much to start back up with my tarot readings again. Before our setback with my surgery and now this move I was giving tarot readings by email. I have a site and everything but because it's been awhile since I've been able to do readings I know I need to do some advertising but with my husband being the only one with income right now we don't have much room right now for anything extra. So What are some good suggestion's for free/effective advertising. Im not on twitter and I don't have much of a following on facebook as I only really use it as a way to keep in touch with family members that live out of state.
