Normally after you select a flight, on the "Trip Summary" screen before you actually purchase the ticket, there is a section at the bottom:
clicking on the "Fare Rules" link brings up a popup with tabs for "FARE RULE SUMMARY", "FULL FARE RULES", RISK-FREE CANCELLATION", and "REFUND POLICY".
I say "Normally" because I tested it just now (on a couple different routes, and both logged in and not) and the two fare rule tabs are blank,
so DL IT at work 
EDIT: works on another computer, so must be something about my laptop.
