Automatic currency conversion, part 2

I wrote about the automatic currency conversion system I wrote for the website some time ago. The system works, but there are some issues with it. The biggest problem for me is that the converted price is not always the price at Plimus. Obviously due to a slightly different exchange rate. So I could only display an estimate of the converted price and potential customers could be confused by the difference.

Then Plimus announced that users could use calls to their conversion script. A simple URL with your product ID and the visitor's IP address and you get the converted currency back. I did some tests with their system, and after some PHP tricks it seems to be working. Too bad they do a straight conversion and don't use their own rounding system. But these are both new features, so I expect they will implement this later on.

The system is used on a few web pages for evaluation. It's looking good so far. I'll probably remove the old system this weekend.
