I have seen that some people are selling their clubcard vouchers on ebay, the thing is who ever buys them will not be able to use them. I work on the checkouts at tesco and we are under strict instructions to only allow these coupons if the customer presents their clubcard aswell. The coupons have the customer name printed on the vouchers and the clubcard number, so if u buy vouchers off ebay the name on the voucher will not match your own clubcard. Therefor you would have bought useless vouchers.
