Jordan's Furniture, owned by billionaire investor Warren Buffett's firm Berkshire Hathaway Inc., offered customers a bet of sorts last spring: buy certain furniture items and they will cost nothing if the Red Sox win the World Series this year.

Nearly 30,000 people are four wins away from free furniture.

That's how many Jordan's Furniture customers took a bet of sorts last spring, buying certain furniture items that will cost them nothing if the Red Sox win the World Series this year.

With the Sox now in the Fall Classic as the American League baseball representative, the chances are even better that the ``Monster Deal'' will work out for finger-crossing customers.

``What's neat is you've got thousands of families so excited about getting free furniture and also getting into watching the Sox games,'' Eliot Tatelman, Jordan's president and CEO, said yesterday. ``It couldn't be any more exciting.''

Anyone worried about Jordan's holding up its end of the rebate bargain could rest easy Sunday night: After the Red Sox won, the Taunton-based company quickly aired a TV commercial featuring Tatelman rooting on the team. He shot the 30-second spot last week and was even able to mention the matchup with the Colorado Rockies because the National League championship series ended so early.

Jordan's won't reveal how much furniture was ordered during the promotional period from March 7 to April 16 - some reports put sales at around $20 million - but the company won't take a huge hit from it.

The rebates would be covered by an insurance policy taken out by Jordan's.

The costs of that arrangement were not disclosed.

Money aside, Tatelman is simply amazed the Red Sox are living up to the promotion - at least so far.

``Who knew? It was before spring training when we approached the Red Sox and set it up,'' he said. ``We had no idea it was going to develop into this. How can you predict?''

According to the terms of the promotion, customers had to take delivery of merchandise by the July 10 Major League Baseball All-Star Game. If the Red Sox win, customers must fill out and mail in a rebate claim form.

The deal covers sofas, dining tables, beds and mattresses. Tatelman noted that customers need to remember that similar or accessory furniture items such as loveseats, chairs, end tables, nightstands and bed frames are not included.

``When the Sox win, it's not for everything that everyone bought,'' he said.

Jordan's, owned by billionaire investor Warren Buffett's firm Berkshire Hathaway Inc., has stores in Avon, Natick, Reading and Nashua, N.H. The company started out in Waltham.

Tatelman is delighted by the publicity the promotion is giving Jordan's Furniture, which is the ``official furniture store of the Boston Red Sox'' according to its sponsorship deal with the team.

``It's been fabulous. Nationally we're getting exposure and locally on all the TV stations, newspapers and radio stations,'' he said. ``It's publicity for Jordan's and its fun.''

So, if the Red Sox lose - or even if they win - will Jordan's come back next season with another free furniture promotion?

``We've got to finish this year before we think about next year,'' Tatelman said, sounding like a shrewd businessman as well as a true member of Red Sox Nation.
