There is no doubt that technology has been advancing all around the world. Many things that were only in the realms of people’s imagination are actually being turned into reality. 
    Everyone has heard of buying groceries through the internet and it’s extremely helpful if you feel that grocery shopping is time consuming. Stores like Lowe’s have offered order ahead shopping, which means that you can call in and tell them what you would like and they prepare it for you so all you have to do is come to the store and pay for what you want. The only flaw of this would be that you still have to drive all the way to store to get your things.  
    Tesco HomePlus, South Korea’s version of Wal-Mart, believes that its customers shouldn’t have to take time to go to the store and buy groceries, so they developed a method where the store goes to the people.  Tesco constructed virtual grocery stores in subways/metro stations all over Korea. The “virtual stores” are essentially posters on the walls resembling a grocery store with a barcode under it. Individuals can take a picture of the barcode on their phone and put it on their virtual cart while they are waiting for their train. After a few hours, everything they purchased will be delivered to their homes.    
    “I would definitely use this method but there are some things I wouldn’t buy online, like produce," Ms. Gaines said.  "Canned or boxed items would be what I would focus on buying.  They should do this with toys and electronics. The delivery being only a few hours sounds really good.”
    Others are not so keen on the idea of virtual. A few people feel that although the method seems extremely convenient, it may prove to have terrible consequences. Other people feel that they probably would stray away from this. 
    “Although I can see how this can catch on to our society, as an individual I would stick to the old fashioned way,” Mr. Hinson said. 
    Senior Hee Noh also voiced his concerns.
     “America is already experiencing problems with obesity," Noh said.  "By introducing this new system here, it would definitely increase obesity rates.”
    There are always going to be pros and cons to new things introduced to the public. Since there are still many Americans who don’t own a smartphone, this virtual shopping method may not be as successful here as it is in Korea, where two-thirds of the population owns a smartphone. Another reason that this program may not be effective would be that this country has an immense number of people. It may be rather difficult to send the merchandise in a matter of a few hours. Overall, it’s a wonderful idea but it may need some tweaking when adopted by different places to suit the environment in which it is intended to be implemented.
