No purchase necessary to play. One pick per account per drop; an account is one email address. Every pick wins. Prizes are single-use codes tied to your account email, valid through the end of the 7th day after you win (Witching Hour prizes: until Mon Nov 2, 11:59 PM ET), on orders with a product subtotal of $100 or more ($200 or more for $100 off). One cauldron prize per order. Combines with Buy 2, Get 1 Free, partner/referral codes, other promo codes and store credit. Free vial = one extra vial matching the lowest-priced vial in your order, same size, added to your cart for $0. Free shipping: US orders, USPS Priority on $100–199, or a free upgrade to UPS 2-Day on $200+. Free shipping over $200 is calculated after discounts. Some prizes are limited; when one runs out, its cauldrons hold the most common prize instead.
