Attention weekend shoppers! Saturday and Saturday only, you can save a bundle at Bloomingdales in the home department. From towels to mattresses to flatware, take your pick of some gorgeous goods that have been reduced by up to 85 percent. And if you're searching for a good way to waste time after work this afternoon, today's their preview sale. I think I might be heading up Market Street myself to check out the goods at the San Francisco Bloomingdale's . . .
