What CC services do you take advantage of?

Does anyone take advantage of additional services that your card provides such as travel insurance, concierge, discounts, etc...? And if so, what are they? Any suggestions for making it a habit to review and use these services when making purchases, rather then completely forgetting these perks exist?

I just got the Chase Freedom card and noticed in the packet that I have a Visa Signature card. Upon further research, I get additional perks with my card beyond the 1% or 5% cash back on purchases.
