Just a general advice and help to build your points with Tesco thread.
While worth 1p in store, Clubcard points values are quadrupled when converted to Tesco Clubcard Rewards Vouchers, which include days out, magazine subscriptions, holidays etc; eg, Alton Towers ticket for £7 of points, or a year's Cosmo subscription for £9.
This means if promotional bonus points given are more than a quarter of the goods cost in pence, you're in profit, providing youd have used the reward anyway.
Sometimes this makes it worth buying goods you don't want!
Even if you're not in profit, if there are substantial bonus points on goods you'd buy anyway, it's equivalent to a substantial discount.
