Personal credit card

Business credit card

Note: In order to get enough miles for Kindle Fire (53,400 as of 12/12/11, see more details here) from Delta Marketplace, you would need to apply for both personal and business Delta credit cards and then spend $500 with each card within 3 months. You should be able to use your SSN as business tax ID and you name as the business name if you apply as Sole Proprietor. If you do not want to apply for a business card, you can still use bonus miles to pay a part of Kindle Fire cost (~ 50% ?). Annual fees of both cards are waived during the first year.
