Browse this category for super savings on sergers! Machines in this section are one of two things. First, some customers return their machines for exchange or refund if they decide they want a different model. And second, select sergers are used as demonstrator models in retail stores. No matter which of the two a machine might be, it is first checked out thoroughly by our serger technicians, who have over 40 years experience combined working with sergers. Then they are sewn-off, checked for complete accessories, and are repackaged for discounted sale. Super Saver models come with the warranty listed for each model.
