We found a difficult-to-find wine last year through Marketview Liquor in NY. Ordered a case online and got it shipped to our door in short order. Prices were very good as well.
Here's a link to their web site:

You can enter your search terms in the area in the upper left under their company logo. It turns up a number of results!
Hope it helps!
