Sweet:) on the negative cost purchase.
Wow - 20 cards ARS, that's formidable:)
The $200 to $300 offers can be sweet too and are easier to complete. I haven't done a $100 one yet, could have at my credit union, but since I actually intend to keep my card with them I chose to go with the card that offered the best interest rate instead of the 100 bucks and the rewards. In the long run, that was the smarter choice for me.
But, I'm so looking forward to opening a Chase bank account for a $300 bonus and closing that sucker down the line. I am not interested in a relationship with them - only their bonus money for a cc and bank account. I'm sure they feel equally as warm and fuzzy about me:)
