Discount codes are limited to one per purchase and cannot be combined. If you are having issues with your discount code applying at checkout, please contact us at hello@bisouspets.com before placing your order and we will assist you. Discount codes must be applied at the time of checkout and cannot be applied after the sale has gone through.  If you forget to apply the discount code or the code does not apply due to an error then price adjustments, refunds or credits will not be issued.
