In 2003, I picked up an anthology of Science Fiction Christmas stories - which I must have leant out because this past holiday I could not find the book anywhere. The stories were wonderful - and I have not been able to find it by title or topic. The stories were not all Bradbury - but I visually recall that the book (paperback) was in with other Bradbury books. Maybe my memory is playing tricks on me - I appreciate any help anyone out there can provide -

best wished for all in 2005 -

I found a book for a dime a couple of years ago called "Fourteen Favorite Christmas Stories." They aren't sci-fi, but maybe it's what you're looking for. It contains stories by some famous authors such as O.Henry and Thomas Hardy, and then there are several authors I personally have never heard of. The very last story in the book is "The Gift," by Bradbury. It was a fun book to read over the holidays.

Connie Willis has a book of Christmas stories out too, don't remember the title but shouldn't be hard to find. It's recent, 2002 or so.
