(BNBN)

said sales for the fourth quarter will exceed $103 million, a 36% increase from the year-ago period, but added that it will lose more money than analysts are expecting for the year, thanks to the acquisition of

Fatbrain.com

.

The online book and entertainment products retailer said music sales were strong in the quarter and the company's new DVD-Video store, which opened in July, exceeded expectations.

The company expects to lose $1.05 to $1.08 for the year, wider than consensus estimates of a loss of 95 cents a share. The company attributed the forecast to the inclusion of the acquisition of Fatbrain.com, which analysts didn't figure into their estimates. The company didn't provide earnings guidance for the quarter, but five analysts polled by

First Call/Thomson Financial

are expecting the company to lose 24 cents in the quarter.
