I shop online weekly with Tesco and spend around £140 a time. I usually receive a petrol voucher with the invoice - I don't drive but I pass them on. I went into a Tesco store today and was given cutlery vouchers. I really like the Alessi cutlery and would love some new bits for Christmas. As Tesco have never offered me the cutlery vouchers with my weekly online shop would it be unreasonable to ring customer services and ask for some cutlery vouchers (I need around 30). There are some being sold on ebay if I have no luck with Tesco but I am worried they could be fake ...
