That's equivalent to an 80% APY!! This is, by far, the highest APY- equivalent bonus that I've ever seen for a deposit account. Open a business checking acct. w/ Santander Bank by 7/30, maintain a $2,500 average daily balance for the first 90 days and they'll pay you $500 within the next 30 days. You must physically visit a Santander branch in order to open an acct. It has branches in CT, DE, FL, MA, NY, NJ, NH, PA, and RI.
