Several major acts, including U2, No Doubt, Taylor Swift and the Dave Matthews Band, have already announced they'll offer discounted tickets for their tours this summer — good news to concertgoers during a recession. And now, Beyoncé is following suit: According to a press release from her label, the singer will set aside 2,000 seats for each date on her forthcoming North American tour at a discounted price of $20. The tour is in support of her recent I Am ... Sasha Fierce LP.

After already selling 1,000 tickets per show for the special low price, the last 1,000 discounted seats for each show will be made available to the public on Friday through Ticketmaster (with the exception of the artist's four-night residency at the Encore at Wynn Las Vegas).

Also at the concerts, fans will have the opportunity to participate in food drives, as part of the Show Your Helping Hand initiative. This national hunger-relief campaign was created by General Mills Hamburger Helper in partnership with Beyoncé and her Survivor Foundation.
