The Original Factory Shop posted a record sales rise of 20% in the six months to October 31, as the discounters continue to defy the tough trading conditions.
Like-for-like sales were up 4.5% for the six-month period.
The Original Factory Shop opened its 100th store in Deal (Kent), this week, and said it was on target for 20 new stores by the end of the current financial year.
The Original Factory Shop chief executive George Foster said: "Despite the difficult retail climate, the last six months have been our strongest yet and the result of a cohesive property strategy with a diverse and dynamic product mix. We're gearing up for what could be our busiest festive season yet. Consumers are looking for good value deals and we can offer them just that right on their doorstep."
