Sorry if I insulted you, but some folks just don't follow up the links provided.
In answer to your question, it $10. This applied once per user. Hence if you bought AnyDVD first instead of $39 it was $29. However if you later applied for discount when purchasing CloneDVD or CloneCD & applied for discount you would be told discount had been claimed/expired. So it still pays to get all three if you think you're likely to use them.
