Whenever I travel to Arizona, I stop in citrine. Gorgeous store, super helpful staff and awesome products. The experience is awesome and the products are natural, nontoxic, green and effective. They also have an awesome YouTube channel where you can see demos and reviews of specific products.
I've used their online store and they send samples of high end products, help with applying codes/gift cards and follow up. I love these ladies and will always stop by when I'm in town.
