What is another phrase for kill two birds with one stone? Or another term that implies similar meaning?
There's an old, idiomatic expression which might be used for more than two results of the action:
one fell swoop per wiktionary
- to stop two mouths with one morsel
- to get two son in laws with one daughter
- to kill two flies with one slap.
- to make two friends with one gift
- to take two pigeons with one bean
- to carry two faces under one hood
- to have two strings to one bow
Twofer is the short form for "two for one."
Definition: Arrangement in which a single expense or amount of effort produces two returns; Person or thing that has two desirable attributes normally present singly, i.e. something that satisfies two criteria or needs simultaneously.
Example: Going to a wedding in New Orleans during Mardi Gras was a twofer.
EDIT: I realized that @user662852 had already made this proposal :(.
There is the outdated saying stop two gaps with one bush:
which is the equivalent, probably earlier version of 'killing two birds with one stone'.
(Allen's Dictionary of English Phrases)
Another approach would be :
as a bonus or on top of or extra benefit
also, but even less directly you might stretch towards side effect etc
Yes these generally refer to additional benefits resulting from what looks like a focus directed at only 'one of the two birds' , yet this approach is very common ... and very very frequently the reality is that on the surface a given plan ~will~ seem more directed at one target yet happen to include the other.
