I would also suggest making sure you really need new springs before you go down this path. Changing front springs is not fun and somewhat dangerous and you could end up with a ride height you don't like.
This is true. Coil springs do not wear if installed correctly. At most, they'll have some creep which drops ride height slightly over time, but spring rate itself will not change. (Which can be why some are surprised if they replace well aged springs with new, and the vehicle sits a bit higher. Or so-called "lowering springs" end up at the same ride height). And coil springs should not fatigue if made correctly (or some idiot hasn't hit them with a torch).
The only reason to change springs is if you want a different ride height, you've changed something that adds/reduces weight significantly, or you want to change the handling characteristics (e.g. higher spring rate for performance, at the sacrifice of ride quality).
Leaf springs are different story.
