The main shopping centre in Sale, the Square Shopping Centre, was constructed in the 1960s. Following the Trafford Centre's opening in 1998, it was expected that the centre would suffer, but it has since prospered. In 2003 the Square Shopping Centre underwent a £7 million refurbishment, a major part of the redevelopment of Sale's town centre. It was sold for £40M in 2005, by which time the Square had experienced an increase in trade and demand for tenancy that had led to an increase of 70% in rental income. The town's economy expanded to the extent that in 2007, at a time when the rest of south Manchester was oversupplied with office space, Sale's available office and commercial space was at an all-time low because of high demand.
