DOWNLOADABLE GOODNESS? how?

[Ggurl]

Hi I'm pretty new, so i dont know if this was already asked, but most likely it wasnt because I couldnt find it any where. Anywyas my question is:
I live in barbados and I want to know if it is possible for me to download the sims 3 directly to my computer, or is that only possible in the US? And also if I can ship my stuff to Barbados or do I need to do kind of a relay system in sending it to someone I know in the US/ Canada and then let them send it to me.
Also, this is not exactly technical is the sims3 available in the GameStop stores?
