Just got the ad in the mail. I never use my Discover, but I got a letter with this deal. Charge $200 or more per month each month from June 2010 to October 2010 and get $500 cashback bonus. That is on top of cashback bonus you'd get. In fine print it says you must reach $2K per month. If I charge everything from gas to bills to grocery to diapers to new baby furniture (2nd due in July) ... everything, I can reach that. I always pay off in full every month (I currently charge everything to a card linked to my child's college savings account for rewards, but it can't hold a candle to a free $500. Anyone do this? It says you must call to enroll. I also see that you can get up to 5% with Dicover back now in one category, but in fine print it says you must sign up for each 5% program. Anyone have details or experience on the 5% deals or the $500 deal? If I call do I find out this is a scam with an up-charge or something? I have had the card since 1999 but never use it. It might not have been used in 3 years.
