I found out via one of our blog readers that the ACKC in Alexandria no longer carrier Couture Cupcakes. When I called up ACKC to confirm this, the manager said that “people stopped buying them here, so we had to discontinue them." The DC store does still carry them.
Couture Cupcakes, by the way, has changed its name to The Blushing Bakeshop. Their website however, still uses the same internet address. Apparently the name was changed because Couture Cupcakes plans to offer a line of gifts and baking products.
