For books check your library first to save money. Any book store can order in books for you though. I suggest avoiding Silver Ravenwolf for your year and a day, she's got a negative reputation. For items, you can buy things like a knife and covert it into an athame, it buy your own herbs to grow, there is a shop on this site you can use. Look in your area for new age or occult shops you can get what you need their. Just remember you don't need to buy name brand items, a simple journal can be used as a Book of Shadows, just as easily as a hand made leather grimoire being sold at an occult shop.
