The problem with shopping and languages

I thought of the perfect birthday gift today for a good friend.  She's interested in learning Spanish, has a natural curiosity about the ins and outs of colloquial terms, and has successfully learned a language on her own.  She can sling slang in two countries so I thought I'd pick up a set of Pimsleur CDs or audio tapes so she could get started in another.  Great idea, huh?

The problem is I have no way to shop for such a gift on-line.  Why?  She's a native Japanese speaker and I wanted to get her a "Japanese - Spanish" set of learning materials. 

Have you ever tried shopping for language aides?  Sites like Amazon, or even Pimsleur make the assumption that since you're coming to the site via an English IP, then you must be looking for an "English - Other" set of tools.  There's no way to change the context of what I'm searching for to get rid of this underlying assumption.  It's frustrating.

In the past, I have purchased items from Amazon's German site but that only works because I know what I'm looking for, because the interface between the two sites is similar, and because I can use Babelfish to figure out words I'm unfamiliar with.  It didn't work well in this case.

I don't know of a brick and mortar store to consult, so I think this idea is toast.  I'm back to square one for ideas! Ack!
