STARBUCKS at convenience store

The STARBUCKS caffee and latte began to be sold at convenience stores in Japan. Accordig to the advatizement, the taste and quality are the same as at the shop. But the latte at convenience stores don't have foamed milk, so I can't believe the same. The STARBUCKS coffee or latte are more expensive than the competitive drinks. I thought the price was for the brand. Frankly, the taste was like the same as the competitive products. I wonder if this drink become big.
