It seems no one post this promotion.

I have a post about the promotion from Sony Rewards. (here)
I was not very sure about the promotion at that time, so I added
“Possible” at the beginning of the title. Today I called sony rewards
customer service (866-556-7669) today and verified the promotion.

In order to receive the 10,000 bonus points, you have to: 1). You
must have a Sony Card in good standing and an active Sony Rewards
account. If you don’t have the rewards account, you can create one to
become eligible. 2). You must sign on to Sony Rewards at least once
during the promotion period (2/15/2008 - 3/31/2008). 3). You must
charge a total of at least $500 in purchases on the Sony Card during
the promotion period. The purchases do not have to be Sony product.

The link sony.com/sonycard/flyfree is not to assure you that you are
enrolled in the program. However, it’s to tell you that there’s a such
promotion. This promotion applies to Sony Card Accounts automatically.
You won’t get any confirmation information from sony rewards. I was
also told by the customer representative that the free companion ticket
was also a part of the promotion starting from April 1st and you only
have to spend $300 on that card to get a companion ticket.

If you can’t spend more than $500 on this card, I suggest you buy
some gift cards from Wal-mart, Target, bestBuy or Amazon.Com. The
10,000 points will be your reward for spending $500 on Chase Sony Card.

What Can We Do with 10,000 Points?

The Sony NWZS615FRED/PNK 2GB Walkman Video MP3 Player is
the best bet. This video player will cost you $92 at Amazon.Com. At
Sony Rewards, you can redeem this video player with only 9,995 points.
Or you can consider the 815 version which will cost you 2,000 points
more.

You can also consider the Sony CMTBX1 CMT Micro Component System with MP3 Playback which will cost you $99 at Amazon.Com. You can redeem it for only 9,995 points at sony rewards.

You can also redeem 5,000 points for a $50 Blockbuster gift card.

If you don’t have a sony card yet, you can apply a new sony card through this link and receive 10,000 bonus points.
