WESTPORT, Conn. -- At Albe Furs, they're not too worried about after-Christmas returns. In fact, like many other upscale retailers, the post-Christmas period has turned into a time of happy returns. Along Connecticut's Gold Coast, not many customers are asking for refunds, and those who do bring back merchandise usually end up spending more. At Albe, a customer called on his cellular phone Christmas Eve looking for a red fox coat for his wife. The day after Christmas, his wife returned the fox, but bought a mink -- bringing the purchase price up from $2,500 to $4,500.
