Anything that forces disclosure is good.

Even the best exposed prechecks are bad, but tempting to those trying to milk every penny. The stats will show you why they do it.

But I could absolutely live with nothing but unchecked cross sales. To me that's not really different from what amazon does. If a user has to actually take action to say "yes, i want to buy that too", that's pretty solid.
