<P> In the second half of 2008, Mars UK reduced the weight of regular bars from 62.5 g to 58 g . Although the reduction in size was not publicised at the time, Mars claimed the change was designed to help tackle the obesity crisis in the UK . The company later confirmed that the real reason for the change was rising costs . In 2013, the "standard" Mars bar was further reduced to 51 g . </P> <P> In the UK, most Mars bars are still made at the Slough Trading Estate . </P> <P> The worldwide Mars bar differs from that sold in the US . The American version was discontinued in 2002 and was replaced with the slightly different Snickers Almond featuring nougat, almonds, and a milk chocolate coating . Unlike the American Mars bar, however, Snickers Almond also contains caramel . The US version of the Mars bar was relaunched in January 2010 and was initially being sold on an exclusive basis through Walmart stores . The European version of the Mars bar is also sold in some United States grocery stores . The US version was once again discontinued at the end of 2011 . In September 2017, Ethel M Chocolates, a gourmet chocolate subsidiary of Mars, Inc. launched the' original American recipe' of the Mars Bar in their stores and on Amazon.com . </P> <P> The international and Canadian Mars bars are very similar to the United States Milky Way bar, which Mars, Inc. also produces (not to be confused with the European version of Milky Way, which is similar to the United States' 3 Musketeers). </P>
