The other reason they cite for raising the price is that their "material costs" are much higher than they expected. Could that have to do with the fact that we've seen a lot of figure replacements in their run so far? These things can get pretty expensive when you have to make two for every other order.
Is $130 too much for you or are you still interested? From the beginning, Figureprints has been working around the clock making these, so even if they lose a little business over the higher price, maybe it'll help them keep up with demand better. And if the new price doesn't work out, maybe we'll see them cutting back again (or offering deals via Blizzard or someone else).
