I didnt know about any of them, I just rang customer services to see why it wouldnt even let me log in to my account. Turns out they had my wrong address which is why I wasnt receiving any vouchers to start with
Ive only started using Tesco my last 2-3 shops, before that I used them about twice a year when I go on holiday (self-catering). We usually shop in Sainsburys on the bus but the last month or so I've started doing it online. I've got vouchers going back to 2009!
I love Tesco vouchers. So far have had 2 flights to Paris,2 stays at Hilton hotels for family been to Legoland and Alton towers and various days out. Also get subscription to Prima magazine every year for me and mum. Have £210 at moment hoping to change into airmiles for trip to Paris.
