Actually, the alternatives will make the price skyrocket in CA (it might make the prices drop slightly everywhere else though ). That's why so many fast food restaurants are slow to adopt trans-fat free frying oils.

Trust me, I know, I'm a driver-salesman for the world's largest bakery supply company. Take our cinnamon chips for example... The old trans-fat 30# cases have been $70-80 for the last several years. The new trans-fat free went from $120/30# when they were first available a year ago to $150 now, and the bakers dont like it because it spoils faster, and turns green before it spoils. As for trans-fat free fryer shortening, nobody wants it because it's about 30% more expensive than the old stuff and it also compensates the taste of the food, and the food wont stay good as long. Seriously, we sell about 25 cubes of trans-fat shortening for every 1 cube of trans-free fryer shortening.
