in fact, comparing with last year you reduced the price for your product...

however you do request 150 Euro for a disc (?)

- there should be quite a reason to pay such fee... if from the other hand all PC users are looking for only free of charge information which as the matter of fact is available not only from current source.

... i was, myself so much curious to pay for one an year ago, however after I got through the content of your presentation files, i gave up with that.
would i suggest you conduct a survey on what you offer (at least free pdf downloads) to attract customers in future...?
however it is all up to you.
with respect to your meantime developments
