It is a real tricky thing to do to have a multi-language website.
I mean from the Search Engines point of view.
if you want to rank high for both english and let say french keywords you will need to work almost double.
Not impossible, just more challenging.
1/ get a shopping cart (like the one we use) that is multi-languages and also multi-languages for SEO (page titles, meta tags, ...)
2/ place a clear indication on your website that the software is only supported in english.
3/ On each page, place a real link to the home page of the other language, so each language can be easily crawled by SEs (drop down menu selector often do not get crawled by SEs)
