The Triangle's last two Borders bookstores will start liquidation sales Friday morning, with discounts up to 40 percent off.

The deals will include all merchandise, including books, calendars, puzzles, CDs, DVDs and more. Borders also will sell store fixtures such as lights, shelves and chairs. The discounts are expected to increase over coming weeks to clear out as much as possible.

There is a large Borders in the Six Forks Station Shopping Center in North Raleigh, and a much smaller one available only to ticketed passengers at Raleigh-Durham International Airport's Terminal 2.

The Borders bookstore at Raleigh-Durham International Airport, which was spared when the bankrupt chain closed other local stores, has dodged another bullet.

Borders Group on Thursday asked a bankruptcy court for permission to close 51 additional stores. The RDU store was on that list, but late Thursday night, Borders spokeswoman Mary Davis said that the location is no longer in jeopardy because RDU agreed to extend a lease-negotiation period.

She declined to provide further details.

"The caveat to that is we can never guarantee a store will remain open indefinitely, but the landlord agreed to the lease extension," Davis wrote in an e-mail.

There was some delay in receiving paperwork from Borders, but RDU agreed to give Borders more time to decide whether to accept or reject the lease, which runs through 2015, said RDU spokesman Andrew Sawyer.

The Borders in RDU's Terminal 2 opened in 2008 and has been one of the most successful retail spots at the airport, Sawyer said.
