BLATANT RIP-OFF?

I have been looking at noise reduction software, and basically there are two products on the market, namely Noise Ninja and Dfine from Nik Software. I opted for Dfine because it is slightly easier to use, and I use other Nik Software products BUT HERE IS THE CATCH. If I could buy the download in the USA it would cost me $79.00 which is just below £50.00. Because I live in Europe I have to buy from Germany, and it is €119 which is around £107.00. We are talking about exactly the same product which is downloaded from the same place - I am not talking about hard copy, but a computer download. I have contacted the company by telephone, but they can offer no explanation at all to me, and I they refused to take a message for the sales manager to call me back. I think this is a blatant rip-off - I don't know about you!
