Discover is offering a $100 signup bonus on its Discover Business Card when you apply now. The card also currently offers a 0% intro APR on both purchases and balance transfers for 12 months with a balance transfer fee of 3% (min $5, max $75).

Unfortunately, the utility of the card’s most unique feature, “PurchaseChecks”, has almost completely vanished. PurchaseChecks, which allow you to write checks to merchants that don’t accept credit cards, are no longer subject to the promotional interest rate, and do not have a grace period.
