If people are selling their Book of Shadows, that is about the only place. And even then, they'll have much more than just spells. And then there is the problem with being able to actually read it. I suppose there are more places, but the best place to look for the spells is within yourself, because that is where Gaia speaks, and you will be speaking straight from your heart.
barnmes and noble is good place to get books on wiccan practice that's where i got 3 of mine but otherwise off of the internet on a good lagitament site that wont take your money. if you cant find one you need to hang yourself on the east side of your room so that the demons of the east can eat your soul so quick you wont even feel it
