Quiznos franchisees have filed a class-action lawsuit accusing the sandwich shop chain of misrepresenting the chances of financial success to prospective owners.

The lawsuit, filed Tuesday in U.S. District Court in Denver, lists 41 plaintiffs and seeks unspecified damages. It alleges, among other things, that Quiznos saturates areas with too many stores; requires franchisees to buy unneeded items, sometimes only from certain suppliers; and requires that franchisees accept coupons without reimbursement from the Denver-based chain.

Similar lawsuits were pending in Illinois, Michigan and Wisconsin. The class-action suit was filed the same day the settlement of a suit filed by a Texas franchisee was announced.

Quiznos Chief Legal Officer Richard Emmett said Quiznos had settled three other lawsuits in the United States and one in Canada, and was addressing franchisees' concerns.
