Discover - Credit Card Review

I have had a Discovercard since I was a teen, to learn how to save & not buy what I don't have money to pay every month.  Mom taught me well since I have a perfect credit score.

But 2007 Discover is a CHEAP card.  The 5% gasonline cashback now has a ceiling of $100 a month.  So forget any auto maintenance in that since any other purchases charged get only .25% til you hit $1000, then .5% til $3000 is hit then you get the 1% advertised.

Guess they do not want me getting 7 free Blockbuster movies a month ($20 cashback getting me $35).

So when I am over $100, I just charge to my Norweigan cruiseline Mastercard that gets me 3% a month cashback towards cruise fare, or AMEX Blue for air miles.
