How to get Rosetta Stone in the US?

I always struggle with the way of learning English.
The list of what I have tried is here;
Studying grammar using texts,
Having conversation with an English teacher,
Checking my English using Grammarly,
etc...

The next challenge might be Rosetta Stone.
However, I could not find the English version at Target.
Of course, I could find the Japanese version. 

The best way of getting it must be Amazon.
Everything that we want to get is on Amazon.

One of the advantages of Rosetta Stone is to check your accent.

Official Rosetta Stone

From my experience that I have stayed for eight months in the US, using correct pronunciation is important when we talk with native speakers.
If you say beige without any cautions, no one understands what you mean.

To check my pronunciation using Rosetta Stone will be my fun.
But, my wife may say 'how much you spend money for learning English'.
