3.50 pound Tesco Clubcard "Every Little Helps" voucher

£3.50 Tesco Clubcard "Every Little Helps" voucher - Tesco Clubcard (commonly referred to and branded as Clubcard) is the loyalty card of British supermarket chain Tesco. The Clubcard scheme operates in the United Kingdom, Ireland, Czech Republic, Slovakia, Hungary and several other countries. As of 2017, there were over 17 million users in the United Kingdom. History In 1993, Terry Leahy asked the Tesco marketing team to investigate the potential of loyalty cards. In the past Tesco had run Green Shield Stamps as a promotional tool which rewarded people for visits and spending, but gained no customer information. The initial team researched programmes across the world and developed a proposal which showed that a loyalty card could be very effective. The key change since the days of Green Shield Stamps was the ability to track individual customer behaviour cost-effectively using a magnetic stripe card. In 1994, Grant Harrison attended a conference where Clive Humby from marketing firm dunnhumby was speaking. Dunnhumby was already working with clients such as Cable & Wireless and BMW, and Harrison approached them to help with the loyalty card project. Successful trials throughout 1994 led to the Tesco board asking Harrison and Humby to present to the annual Board strategy session. The first response from the board came from Tesco's then-chairman Lord MacLaurin, who said, "What scares me about this is that you know more about my customers after three months than I know after 30 years."
