I voted reduce package size.

While it's not the same for everything, I do agree with griffin for snack foods. One thing that annoys me with chips is that the servings of the flavours I like are inevitably the larger packs only - I don't really want 200gm, so 150gm (for arguments sake) suits me better. Yes it's inflation & a trick to hide the price rise, but it suits me nicely.

I also prefer it for Transformers; Hasbro have a tendency to make larger toys with more gimmick rather than more "transform" for the extra $$; so I prefer smaller toys anyway.
