Eligible items that customers purchase during the Holiday using a rain check qualify for the exemption regardless of when the rain check was issued. However, issuance of a rain check during the Holiday will qualify an eligible item for the exemption only if the purchased price is paid in full at the time the rain check is issued. If the item is actually sold after the Holiday, the Holiday exemption does not apply.
