(Wine Searcher) - Two-hour wine delivery continues to be rolled out in new US markets.

Working in tandem with its newly acquired brick-and-mortar Whole Foods stores, marketing executives at the Seattle-based Amazon are swiftly adding to the number of markets in which consumers can easily order wine and beer with their groceries.

They have even surprisingly added a number of Texas cities to their roster including Dallas, Ft. Worth, Houston, Austin and San Antonio. Texas is both one of the most lucrative and yet most legally challenging markets to navigate in the US wine sales market. It is riddled with dry counties and virtually has a fourth sales tier.

Food delivery has also been launched in Baltimore, Boston, Philadelphia and Richmond. Neither Amazon nor Whole Foods would confirm if wine delivery would be available in those cities, or comment for this article.
