At my seller, Ilford MG FB, 8x10 (20x25cm) 100 sheet pack, 39 USD.
Interesting, ID11 for 1 liter of stock was (I think) 3,30 USD, now is 3,10 USD.
Didn't check other prices.
I think the chemicals are actually manufactured under license in the US, aren't they (I know the under license bit, I'm sure at least one of my bottles has a made-in-USA on it, but that could just be my faulty memory!)? If so the changing $ rate would have less impact presumably.
Another reason for film/paper to go up more than chemistry would be silver. Simon mentioned at the factory tour (and it stands to reason anyway) that the price of silver was one of the main costs involved in emulsion production.
Silver prices hit (for recent years) record highs in 2006 if the data I've found on the web is anything to go by - $14/ounce in December '06 compared to $6, $6.5, $8.5 for the previous three years. Obviously picking December is rather unscientific, but the general trend was upwards peaking in 2006. I imagine that could have been part motivation for Ilford's price rises in January. (I've no idea how silver trading works; but presumably part of that rise will be accounted for in the weakening of the dollar - maybe trading in sterling is actually a benefit in this instance.)
The spot rate for silver actually appears to have drifted down a little this year, despite the continued weakening of the dollar, so that might be good for Ilford's bottom line. Of course if the stock markets continue to tank people may decide to invest in precious metals, which could see them start to rise again, I guess...
All pure speculation on my part, but interesting stuff nonetheless. Well, interesting to me. Your mileage may vary

. Any experts who want to chime in would be welcome!
