h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

After much searching for a geolocation with currency converter solution for displaying product prices in the visitor's own currency, I came across geoplugin = http://www.geoplugin.com/

It's a totally free (and importantly fast) web service that does all the hard work for you for geolocating your visitor. Nice, simple explanations of how to use it, with working examples and can be used with different programming languages (I use PHP, but they offer Javascript, XML, and JSON whatever that is)

I really like the geolocalised currency converter - so easy to use, and I can set the base currency that my products sell in, so that the converter displays that price converted the visitor's local currency and have it display their currency symbol properly too.

One thing that is really neat that I haven't seen anywhere before (although I don't have much use for it), is that they can also return all the nearby places - you specify the radius and the maximum number of places to return, and you get a whole bunch of useful info of places near to the visitor - great for tourist things

Big thumbs up for geoPlugin

While I was searching for a plugin , I remember www.idiscoverindia.com used to use one Free Currency Exchange , however their service was very poor ,somehow they never responded not even when we wanted to buy a paid version. I hope this one works for us, as we are looking for a solution that can automatically change or display prices in local currency along with our USD prices.
