So I'm sure you have received your '3 weeks of savings vouchers' through from tesco like me. Was just doing my online shop, managed to use all 3 weeks worth of vouchers on one shop, saving me £14 on a £40 shop!
First voucher began with an x but the other two weeks began with a G.
Supposed to use them one per week.
Obviously codes are one use per person per account so can't share the codes but if you have been mailed them it's worth trying!
