Thanks for sharing info on this card. We hate Sams and dropped our membership and just have Costco. I really like how the employees at Costco act--they are so much nicer to us than Sams or Wal-Mart employees.

I do charge nearly a million a year for business, and could be tempted on this, until I realized that I would need a 200K limit in order to do all my charges on this and maintain nearly the same level of float I have now. It would actually be a good deal less float since with multiple cards you can work the closing dates to always get at least 45 days of float and often close to 60. I'd have to calculate the cost of the lost float but I am too tired right now to do that accurately. I've never had Discover and not sure how hard it would be to use. So I might give it a try. I think even at $250,000 a year in spending it would be worthwhile to do. Of course maxing it and getting a check for nearly $20K is a very attractive thought! Does anyone know if these type of rewards are taxable?
