This is similar to the Tesco double-up offer which runs from time to time.
If you have accumulated any Sainsbury Nectar points, it's a great offer. You only have till this 13th May to get the voucher but it's valid to use in store till 20th May. I had about £15 worth of points which doubled up to £30. I spent mine on Beauty products and bought about a year's worth of shampoo, shower gel, soap etc (Maybe a slight exaggeration, but it will last ages!) Can choose various categories eg Home, Tu clothing, Magazines, Electricals, Beauty.
