Reg free item in bill amout reaches a value

For the season business.I like to give a 1 Liter CoolDrink free when they purchase for 1000rs.
if they purchase for 2000 I like to give a 2 Liter Cool drink free.

But one important point is…

the value for the free item(Gift ??) should be calculated based on particular items not for all the items in the store.

pls guide me.
