Fuji isn't the only company raising their prices.
Kodak roll film has gotten quite a bit more expensive too, while Ilford seem to be holding their prices for now.
Comparatively, Acros still seems like a great deal in rolls. For sheets, well - I think the sheet film is imported via different channels than the roll films, which is what's causing the pricing disparity. Fuji also makes black and white photo papers that we never see in the States, and chemistry. There's an online business that sells them as direct export to customers, but I think their prices are close to ridiculous.
