Unless you are having a specific problem with your struts, I would agree with andyg. Everything I have heard from mechanics and others indicates that, in almost all cases, modern struts can be expected to give good service for a very long time, and it is highly unlikely that replacement is warranted until well after 100,000 miles.
Put new struts on and you are probably wasting your money.
