We really are in no position to be telling the film/paper companies how to price their product, so I'll consider the debate over how much the silver price actually affects film price to a business/academic debate.
If I were running a film business or any business seriously affected by raw material costs, I'd suspect their price changes are stepwise functions compared to the less even increases of raw materials. Perhaps if costs jumped 30c over several months, their increase of $1 could be a step up to cover past increases, current (30c) increases, and some future elbow room for raw material increases.
Shipping methods to avoid needless xraying may also be increasing costs. With increased security and synthesized paranoia, there are more hoops to jump through for efficient shipping and fewer options.
Ilford and Kodak are top tier film companies, and Ilford is probably the top tier paper company, so it's more of a quality choice rather than an ultra price sensitive commodity.
