Query: AN OUTRAGEOUS RIP-OFF!

This item is really a waste of money. For 20 or 30 dollars you get a vocabulary of at most 100 words. Want to learn some more? Then you must shell out another 20 or 30 for the "intermediate" one, and so on. As Amazon discreetly omits any description of the product on its web site, I got the impression it was a language course, because it said "beginning level". But it turns out that it's more like a phrasebook. There's no grammar, no explanations, just a bunch of phrases and words to learn. This is by no stretch of the imagination "learning" a language. The most insidious thing about it is that they could have crammed all the 3 levels onto one CD, but that would have damaged their profits. Is this one of the blessings of the free-enterprise system we hear so much about? There are 2 books for actually learning Khmer that have a CD or cassette. I'm going to get one of those.AN
