If you return part of your order, please note that the refund amount related to any promo code used may be adjusted accordingly. Promo codes are typically applied proportionately to the items in your cart. Therefore, if you return a portion of your order, the promo code's value will be recalculated based on the items that you are keeping. This means that the refund amount may be less than what you initially received due to the adjusted application of the promo code.
