A few beers and a couple of PHP (that's computer programming code for you non-techies) headaches later, a little pet project of mine is now officially live. I think you may find it somewhat useful, as (in its currently very rough stage) the website grabs silver prices from all the online bullion dealers in real time for a quick price comparison.
I'm also recording all the premiums and information in real time so we can have some real premium-price data to work with (my plan is to expose in concrete terms the disconnect between the paper and physical market for bullion). As always, I'd love to hear some feedback you all might have, or any features you might be interested in seeing.
All the best!
