Discover - visa Review

I began using the Discover Visa in July of 2009 primarily for use on a family cruise and Florida vacation.  One of the things that appealed to me was the "cash back" package that came with the credit card.  I have other credit cards with the same amount of interest and they do not offer any rewards.  I have been very satisfied with the Discover Card.  It can also be used for cash advances and there are checks available if one would like to use a check.  One thing I did was to pay off other cards so that I could increase immediately the amount of "cash back" I woulld receive because the interest would be the same.  The only negative I have found about the Discover Card is that there are some merchants and institutions that do not accept Discover for some reason.  It has not created a hardship because the places that do not accept the Discover Card are usually merchants that have just gone into business or are very small and haven't applied to accept Discover.  To date I think I have almost $50.00 cash back on the account.  I will continue to use this card as my only credit card.
