You earn 1 loyalty point for every $20 spent, which is credited to your account. Each point is the equivalent of $1 and can be applied to your next order at checkout.
When you get to the checkout, your current loyalty points balance will be viewable, and you will have the option to use some or all of your points balance towards the cost of the order.
You must be logged in to your account at checkout to have your loyalty rewards available. Click the My Account link at the top-right of the website to log in.
