In case you enter a discount code during checkout that doesn't exist or isn't currently active, then you can see the message: “Unable to find a valid discount matching the code entered”.

Discount codes don't stack. If you have 56% off discount, they can't also use a "free shipping" coupon since Only one discount at a time can apply to a single order at the Macbooster site.

To avoid this problem, you should check out carefully Macbooster promo code before that promo code could be expired, some promo codes are tied to a minimum purchase, a first-time purchase, or tied to geography, and other reasons.

Usually, Coupon Stacking is not allowed at Macbooster. However, the store will surely give out notice if available.

For the first purchase at Macbooster, you can save up to 56% with our coupons, but you even can save more when buying on Special Discount Occasions.
