its also dipping down into the cup which reduces the "extra" and depending on how you fill it, theres likely to be either some air around the edge of the lid if you put it on first and fill, or a huge mess from pushing the lid down into slurpee. Plus its MUCH more likely to spill.
Think i'd rather pay the 10 cents extra for a bigger cup
