At Nordstrom, sign up to become a Nordstrom Rewards Member and receive a $10 Nordstrom Anniversary Sale Promotional Certificate for free. (It's free to sign up.) You may use the credit during Nordstrom's Anniversary Sale, which begins July 22 and runs through August 7, which is also when the credit expires. That's the first such bonus we've seen with a rewards sign-up at Nordstrom. Last year, we saw discounts of up to 43% off during the Anniversary Sale. Deal ends July 10.
