Sainsbury’s shopper reveals trick to get money off at the till by paying for a single item first

Here we round up what saving programmes you'll find at the big brands.

• Iceland: Unlike other stores, you don't collect points with the Iceland Bonus Card. Instead, you load it up with money and Iceland will give you £1 for every £20 you save.
• Lidl Plus: Lidl customers don't collect points when they shop, and are instead rewarded with personalised vouchers that gives them money off at the till.

• Sainsbury's: While Sainsbury's doesn't have a personal scheme, it does own the Nectar card which can also be used in Argos, eBay and other shops. You need 200 Nectar points to save up £1 to spend on your card. You need to spend at least £1 to get one Nectar point.
• Tesco: Tesco Clubcard has over 17million members in the UK alone. You use it each time you shop and build up points that can be turned into vouchers - 150 points gets you a £1.50 voucher. Here you need to spend £1 in Tesco to get one point.
