Bookseller Borders Group Inc. (NYSE: BGP) continues to bleed money even with the release of the latest Harry Potter volume. If anything, the losses, already substantial, are getting bigger. Despite the fact that consolidated sales as reported in 2Q 2007 results were up 10% to $945 million, the company still posted a net loss of $25 million, or $0.43 per share, a 25% bigger loss than Wall Street had anticipated. Things have gotten so bad that CEO George Jones remarked he was encouraged by flat sales at Waldenbooks. For the last 7 quarters, Waldenbooks' same-store sales have fallen.

Borders stores posted a total sales increase of 9.7%. Excluding Harry Potter, organic sales growth -- a misleading term in this instance -- was less than half of 1%. This is an expensive business model that is not working. In an effort to lure customers into stores, Harry Potter was sold at a large discount to match prices at discount chains. Administrative expenses increased a bit, but debt increased by almost $200 million, to $663 million. No wonder Borders is now negotiating to amend its credit agreement with its banks and considering the possibility of selling its Borders International segment, which still somehow posted a $10 million operating loss even while total sales increased 31% to $170 million.

Waldenbooks is in an even worse situation. Total sales declined 7.7% and operating losses were the same as one year ago, meaning the chain has made made no improvements to its bottom line situation. BGP shares began the year trading at $22.46, reached a high of $23.41 in late May and have been tanking ever since, closing at $14.66 on Thursday, down $0.28.
