It is only possible to have one voucher active on your account at any one time. The addition of new vouchers will terminate any unused vouchers, or ongoing discount vouchers, that are resting on your account.
For example, if you have an ongoing 10% discount voucher and then apply a £15 Tesco ClubCard voucher to your account, the ClubCard voucher will terminate the 10% discount voucher. This is the way that our voucher system currently operates, but if this changes in the future you'll be the first to know.
While it's not possible to use two vouchers simultaneously, it is possible for you to use a voucher and bonus credit from our feedback system and our friend referral scheme at the same time. You can find out more about earning bonus credit by leaving feedback here, and via our friend referral scheme here.
