Only one code may be used per order. Codes may not be used if there is a site-wide automatic discount in place such as a BOGO offer, spend and save offer, etc. If more than one code is entered at checkout, the better code will apply to your purchase. HomeWorx Customer Service will not be able to accommodate stacking multiple promo codes to your order due to systematic limitations. If you have more than one promotional code to apply to an order, we recommend placing separate orders to maximize your saving.
