One of my favorite Frugal Witch tips is to go to the library instead of buying new books ( I have to admit I am soo guilty of buying every book I see, but it is something I afford myself). I just checked and my local library has over fifty titles available and I live in a very smal county.
If the library doesnt work as any of your witchy friends to loan you a book or two, I am sure they would be more than happy to do so.
Another tip is the dollar store as mentioned before and I swear I will do a dollar store trip and show you some things you may have never even thought of using.
You can get candles, oils, dolls, herbs, etc. The possibilities are endless.
