The last Friday of November is "Black Friday" in the United States, when big sales are held all over the country. Unexpectedly, guns were a big hit this year. According to statistics released by the FBI, 175,000 guns were sold on Nov. 28, 2014.

According to the latest statistics published by Gallup Organization on Oct. 31, more than 70 percent of interviewees are against strict gun control in US. Even though the frequency of gun-related assaults is getting higher in the United States, the number of people purchasing guns has shown no sign of falling.

All you need to do is submit an application to get a gun

The sales of guns on Black Friday was astonishing. CNN reports that at least 3 guns were sold in every second on Black Friday, almost triple the normal daily sales.

From the Sandy Hook Elementary School shooting in 2012 to this years' high school shooting in Seattle, all these gun-related killings did not discourage people from buying guns. On the contrary, more and more people are keen to buy.

Supermarkets like Walmart not only sell guns in stores, but also provide online services with free shipping. After the buyers submit an application, they can buy a gun just like any other merchandise online. A .38 caliber S&W revolver costs only 399.99 dollars online.
