A tip if you want to get Tesco Clubcard points with the Linx Vision:
Tesco currently have a 150 bonus Clubcard points (worth £1.50 at face value) promo when you purchase branded gift cards - including Argos and Currys. If you buy £150 of gift vouchers to pay for your Vision, you will get 450 bonus Clubcard points, plus however many you get for spending £150 in Tesco. These points can then be doubled, especially handy during the current double-up promo, or even quadrupled for days out or eating out. Its not a huge saving but if you collect Clubcard points, this at least gives a little extra back!
