It said the chain sold the cigarettes at four prices throughout the country - £1.92, £1.94, £1.96 or £2.02, but not £1.98.

"But by and large, they aren't the kinds of books the chains can sell well."

Since 2006, the chain has sold exclusively fair trade coffee.

As of 2009, the chain sells an average of 20,000 per day.

By the late 80's, the chain had about 40 stores and sold its hot dogs in supermarkets.

The chains not only sell socks but also manufacture about two-thirds of what they offer.

Most chains don't sell it, except on special order.

Some other chains, too, will sell only multiple units, which means a bigger investment.

Goodman says the chain has sold nearly 1.5 million of them to date.

In 1999 the chain sold more goat meat than beef.
