Discover - Credit Card Review

I have had Discover for over 10 years.  It was my first credit card.  I always pay my bill on time each month fully.  I charge everything I can from gas, groceries, to ultities.  You earn cash back and I then turn that into to gifts for others in the form of gift cards.  Saves me bundles on Birthday and Chritmas.  So they are paying me to use their card! Can do a lot over the internet which is great!

Have had them check with me when i was moving because was buying a lot.  Made me feel good they noticed a difference in my buying.

Downside is all the junk mail they send and those checks.  Also, periodic calling for proitection plans.
