Which supermarket loyalty scheme actually feels worth having in your wallet?

Clubcard prices at the till plus vouchers you can boost at restaurants and days out. A national institution at this point.

Nectar Prices are hard to ignore, and you can rack up points at Argos, eBay and the petrol station too.

Digital coupons, spend rewards and the mild thrill of a scratchcard every time you pay. Bargain hunter heaven.

More Card prices and personalised offers, plus a soft spot from anyone who remembers the fivers you used to earn.

You get money back on Co-op own-brand buys and a chunk goes to local community causes. Ethical smugness included.
