Discover - Discover Card Review

I've had other credit cards in the past, but since I got a Discover card, it's the only card I use.  They have the best customer service I've ever experienced.  I really appreciate that they phone me when a charge doesn't go through to see if I'm aware of it and let me know how to faciliate the purchase if I still want it.  Any unusual activity such as a series of small online purchases results in a call to make sure my card is still in my possession.  They even notify me prior to the bill generating if I'm approaching my limit and an over-the-limit fee is about to be assessed.  They provide a user-friendly website where I can make my payments with ease, and they also do payments by phone for which they have frequently agreed to waive the fee.  Although the cashback bonus is very low to add up and the interest rate on this card is a little higher than some of the others that I've had, I am happy to pay a little extra for the top notch service I receive.
