Recently, while looking for a wine, I stumbled across the website wineaccess.com. It requires free registration and has a number of features, including a search engine of wine retailers. I've tried it, and it isn't as comprehensive as wine-searcher.com, but might very well be complementary. For instance, when putting 2002 Ridge Geyserville into both engines, I get 42 hits in wineaccess and 148 in wine-searcher (of which 42 are made available without the Pro version). The wineaccess search engine also tells me which retailers will ship to my location (not a small thing when you live in Indiana).
Anyone had any dealings with them?
