i doubt anyone will truly misunderstand this, but it is ambiguous. churches chicken(a fast food chain) is currently promoting their value menu. i saw 2 signs. one said "9 for $.99" the other said "9 items for $.99". so imagine if you will:
me:hi, i saw your sign. you have 9 items for $.99?
me:great! i'll have 9 chicken breasts.
I guess that is the weird thing about english -- it requires context for what seemingly shouldn't. Oh well... at least with Church's, you actually have to pay first, so you can't make the mistake without being able to undo it.
