I do have a financial interest in my recommendation because I own the business and run it with my wife. I bring this up not as an advertisement but because the selection of stores can be few and the more listed the better.
EverUtopia.com has a wide selection of tools for the pagan. It is geared towards the adult practitioner, so the more dark, gothic and scary items are withheld from our selection. We don't want to give into the stereotype that paganism tends to have.
