Tesco started the first virtual store in South Korea in 2011 and then England. At very first glance, it seems silly, but then after watching the video, it makes sense for people who take subway station daily. This way they can shop on their way to work and after work.
It may not work well in much of US, since we heavily relied on individual cars instead of subway, but it can still work in places like New York City.
What do you think?
