Five Tesco tricks as it launches new double-up

Shoppers who hold a Tesco Clubcard get one point for every £1 spent either in-store or online. But here are the key tricks to hack down costs further...

1. Find £100s of lost Tesco vouchers. First, Reclaim Lost/Unused Tesco Vouchers (can go back two years). We're swamped with successes, a good few over £100 worth.

2. Halve gadget and other costs via new points DOUBLE up. From Monday 3 August until Sunday 13 September, you can swap every £5 of Clubcard vouchers for £10 in various categories, and for the first time in a year on most things in its Tesco Direct catalogue (its equivalent of Argos), eg, Kindle Fire £40 in vouchers, Nutribullet £42, PS4 £145.

   It also works on several in-store categories, including clothing, toys, electricals, home and garden. For how to max this see Urgently boost Tesco points.

3. 1,000 extra points on £60 wine. We've blagged 5,000 codes for new and existing Tesco Wine* customers to use (including 50% off cases), just enter XXHTYA by Sunday (or till codes run out if sooner). Full info in Wine Deals. Pleas be Drinkaware.

4. Turn a £5 voucher into £20. Before doubling, check if you can quadruple rewards. Redeem vouchers via Tesco Clubcard partners and you can get 3x or 4x points' value. For example, £10 becomes £40 at Strada and Café Rouge, £30 at Goldsmiths, or £20 on train tickets. See our Top 10 Tesco Partners review.

5. 'I got £48.30 of Tesco shopping for £19.60' – extreme couponing. Source, gain and hoard 100s of coupons, then combine them for huge discounts on groceries. Supersavingmummy says: "Went to Tesco and the total should have been £48.32, but with coupons it came to £19.60." Learn top coupon stashers' secrets in 20 Extreme Couponing Tips.
