Fixed-price retailer Dollar General is gunning to open a further 600 stores over the next 12 months, creating about 5,000 jobs.

The 5,000 anticipated new jobs come on the heels of about 4,000 jobs created by Dollar General in 2009, according to the retailer.

Meanwhile, Dollar Tree reported record net sales of $5.23bn (£3.22bn) in its financial year to January 30, 2010 - a 12.6% increase compared with the $4.64bn (£2.86bn) it reported last year.

Comparable-store sales increased 7.2% year on year.
