For every order you place, you will receive 1 point for every product you purchased - e.g. for a order of $100 and 27 products, you will receive 27 points.
1 point equals $0.05 or 20 points equals $1.00
Points are saved in your account. Every time you log in, you will see your points.
When you place your NEXT order, you can use the points you collected previously to reduce the new order total. You can use just some points or all of them.
Points are not excluded when other promotions apply, that means you will still earn points even when you used an promo code to get 10% off (just as an example). Usually other promotions exclude each other and you cannot use 2 promo codes for one order. Promo codes do not affect the points you receive for your order.
