For starters this is actually a Russian site. the RU instead of com gives that away.
Second these are Disney copyright images and designs. Although Disney does not have the copyright in Russia they are still illegal in the US. I have read in many places that one COULD get in as much trouble by buying the machine from an over seas dealer as they could from buying them from someone here.
So I would say buyer beware/buy at your own risk!
Maybe instead of doing an embroidery design you could do a cute pieced applique!
