Well of the Moon provides a lovely, cool sanctuary from the bustle of Las Vegas and an excellent selection of herbs, roots and minerals for all of your spell crafting needs. Vicki, Tami and Ayrion are friendly, knowledgeable and helpful with recommendations. They provide a small reference library and a small but well curated selection of books--I have found books from the UK that are almost impossible to find stateside. They also have candles, statuary and lots of other colorful bits and bobs.
They also have a classroom space in the back where they hold a wide variety of classes ranging from Intro to Paganism to Herb craft and Runes. Many are free or ask for a small donation.
