PerkStreet Financial℠ Visa® Debit Card (a sponsor)- When used as a credit card, users can get a rebate of either 1% if the account balance is below $5,000 or 2% if the account balance is above. Additional categories occasionally receive 5% rebates. No interest on the account. Read Part 1, Part 2, and Part 3 of my review for a more complete discussion. 3/7/12 UPDATE: The rules have been modified extensively since this review. Please take the time to understand the changes before you apply. 8/14/13 UPDATE: PerkStreet is dead. Get a credit card instead!
