Reedemable Voucher

Hi<br> <br> Went to Edgars Active Boulders and took voucher received from Edgars which gives me a R250 discount on any purchase over R1000.<br> <br> When came time to pay and redeem voucher manager in store refused to honor voucher as the items purchased were already marked down (on promotion). This despite total value paid was over R1000.<br> <br> No where on vouchers Terms and Conditions does it say that discounted good are not applicable.<br> <br> How many thousands of other vouchers are they not honoring?<br> <br> Regards
