<prompt> Human: No different than threatening to cancel your cable for a discount, you can do the same for your online brokerage, IRA, or other self directed account. For instance, if you have 100k in a Scottrade account, see what eTrade is offering in cash bonuses and call Scottrade to tell them your taking your money unless they match the offer.I just recently used this to get a 300 cash bonus to my account! Theyre only ask was to keep my money there for a year. No requirement, just a request.Happy free money hunting!  <response>: Anyone tried this with vanguard?
