@boomerang,
There are so called professional estate sale companies, they sell many home furnishings and bric-a-brac that they buy wholesale and try to sell at a profit. These companies also tend to do traveling auctions. You usually don't get great deals from them because they run sales frequently and can always sell an item at the another event.
If it was an actual estate sale, I would tell you to leave your phone number with the person in charge and ask them to call you if the item is still available on the last day. If they call, try and have them give you a price by saying "what's your best price on that stuffed elephant chandelier?" If he's still too high- say, "I was thinking more around $xxxx.Would that be fair? I have cash." Anyone really wanting to get rid of stuff will be happy for the deal.
