The £800 has to be spent in the first 3 months at Sainsbury's store or Petrol stations.
5,000 bonus Nectar points for new customers - worth at least £25... more if you double up or use other special offers.
Two credit card offers;
0% interest on purchases for 28 months
0% interest on balance transfers for 18 months
0% interest on balance transfers for 24 months
0% interest on purchases for 24 months
