After years of using the American Express AIR MILES credit card, I recently applied for the American Express Costco Cash Rebate Card. The rewards rate on the AIR MILES credit card is 0.68%, whereas the Costco Cash Rebate is 1.5% (on spending over $5,000 to a maximum of $500).

In the comments to the earlier post, a reader recommended the Citi Driver’s Edge MasterCard. The card, which has no annual fee and offers 2% cash rebate towards the purchase or lease of any new or used car, truck, motorcycle etc. up to $2,500, might appeal to consumers considering a vehicle purchase in the next 3-5 years.

PS: Hunting for rewards is worthwhile only if the entire credit card balance is paid in full every month. If you are planning on carrying a balance, it is better to look for a card with the lowest interest rate.
