Hasn't anyone else heard of the Fleet Cash Dividend Visa card? Cash rebate up to 2%. While the details are not given on the website, other than $500 max per year, the tiers are:

0.25% up to $1,999.00 charged
0.50% on next $2,000
0.75% next $2,000
1.0% next $2,000
2.0% on amounts over 7,999.00

The max $500 cash back will be reached at about $30,500 charged.

At the time I got this card, I did a spreadsheet vs. other cash rewards cards, including AMEX when it was only 1.5%, without the 'everyday purchases to 3%; and also according to my spreadsheet, it paid 1.5% after $4000 at that time. The cards were even at $11,000 but the Fleet card pays more after that. If the highest tier for AMEX doesn't kick in now until $6000, then the Fleet card is even more attractive.

And, I think everyone recognizes you lose more in finance charges to carry a balance than you get back in the extra 2% from AMEX.

Oh, one gripe about Fleet....they started me at a very low credit limit, and only increased it by $2k after 9 months, and will max my limit at the next request, still lower than any other card I have.

On the other hand, I'm approaching the max $500 so I'm switching to another card.
