save (on, for), spend (for, on)

[jirikoo]

Hi fellas.
can anyone clarify me on the difference between verbs with using a preposition:


spend on and spend for

and separately the difference between verbs:

save for and save on

Can you use an examples?

Thanks a lot

Perhaps you should try using these in sentences, so we see the context. Then it is easier for someone to explain the differences.
