TD Ameritrade, the Borg discount investment company made up of TD Waterhouse, Ameritrade and Datek, has a credit card that gets you unconditional 1.5% cashback on purchases, with no annual fee, and no limits. And if you select to deposit your cashback into a TD Ameritrade account, you earn an extra 10% bonus on your rewards, effectively making it 1.6% instead of 1.5%. This is a Visa Signature so you get additional benefits. If you are a current or previous client, they have sent by postal mail a shiny folded postcard size promotion.
