Marine Miles Reward Miles

Our Marine Miles Program rewards our customers with rewards points earned on all purchases. Our rewards program is simple and free.

Marine Miles can be used to apply a discount to your final total. For every pound that you spend you will automatically receive 5 Marine Miles that can be easily redeemed during the checkout process. The more Marine Miles you collect, the bigger your discount. Every 200 miles you accumulate will earn you a £1.00 discount.

Unlike other rewards programs, you're automatically enrolled in our Marine Miles program when you create an account and log in (This is so we can keep track of your points). No sign up forms to fill out and best of all, our Marine Miles program is absolutely FREE! Your points are automatically accumulated for you beginning with your very first purchase and displayed at the top of each page for easy reference.

Please note that you must have a minimum purchase of £10 in order to redeem your Marine Miles. When redeeming reward points, your total discount cannot exceed 40% of your shippable order total before shipping. Any leftover points exceeding the 40% discount will still be available for future purchases. Marine Miles are not transferable. Marinestore reserves the right to cancel or revoke Marine Miles at any time without prior notification. Points are not earned on gift certificates purchases, pre-orders, back orders or phone orders. Marine Miles expire in twelve months. Marine Miles are earned for each eligible item purchased and added to your account AFTER your order is finalised and available for use on future purchases.
