Sainsburys Bank credit card - vouchers

CopperPlate_2

I see that the Sainsburys Bank CC no longer gives you Nectar points as you spend (although there is an offer of 3000 points when you first use the card), and instead they 'regularly' send you booklets with money off vouchers for the store.

What's the general consensus on these vouchers? What sort of money off offers do they give you and are they actually worth using or is it money off ridiculous products like pate de foie gras, hand-picked Spanish-sunshine dried tomatoes (1 kilo bag only) - you get my drift.
