How do I get my $50 PSN credit after my first Playstation Card purchase?

I had hoped to receive my $50 credit the day I registered for the card. After receiving the card in the mail a week after registration, and making a purchase with it, I searched online to find out where the $50 credit was. I ended up calling the number on the back of the card.

I found out:

1. During the registration process for the card, make sure you also sign up for Sony Rewards with the same e-mail you use for both. This will link your card and the Sony Rewards site.
2. If approved, once you receive the card in the mail approximately week later, make a purchase with it.
3. At the start of the next billing cycle after the first purchase, you will receive an e-mail from Sony Rewards (see below).
4. Go to the Sony Rewards website, log in using the information from step 1. Your Sony Rewards point amount will not have changed; you will simply have a credit to purchase the $50 PSN card. When you add it to your cart, the card point price per item cost will be displayed with strike-through font, and replaced with $0.00.
5. Check out your cart and the code will be e-mailed to you, or you can access it from your order invoice through the "get your coupon" link.

Essentially, from registration time to checkout time for a $50 PSN credit on Sony Rewards takes from four to six weeks (1 week for the card to arrive, and assuming you make a purchase immediately, approximately 1 month for the next billing cycle). My Sony Rewards points credit were available one week after my qualifying purchase. Since I made the purchase the day I received the card, the total process, in practice, took a little over 2 weeks, but that might be due to lucky timing based on the billing cycle, or the phone representative was incorrect and the billing cycle has nothing to do with receiving the credit, since it wasn't point-based.

Here is the relevant text from an e-mail sent by SonyRewards after the allotted time passed:

Congratulations. You have qualified for your $50 PlayStation®Network Code.
