Yeah those are called Snickers Almond in the US now. Either way, whether they want a UK Mars bar like in the article or they want a pre-2003 US Mars bar, you can just buy the same thing with a different name in the US.

Mars bars are sold in the US under the name Milky Way. Not to be confused with what’s globally known as Milky Way, which is called 3 Musketeers in the US.
