Creating an account gets you 10% off your first order, on the goods subtotal only, not shipping or the hazmat surcharge. You also get order history and a referral link for store credit.

Every account has a referral link. You and anyone you refer each receive $50 in store credit once you have both placed an order paying $125 or more; if your own order comes later than theirs, the credit lands on their next order. Credit is valid for twelve months from when it vests and applies to goods and the hazmat surcharge, not shipping. They have to create their account from your link, so a guest checkout earns nobody credit, and the link stops counting 90 days after they follow it. Up to ten of your referrals can hold credit at any one time.

Deleting your account forfeits any outstanding store credit.
