Existing Sony Card owners - get 5,000 SonyRewards pts for spending $1.5K anywhere 07/01-08/31 YMMV!!!
Why YMMV?
The offer email had some verbiage about offer being available only to those who received the email. But since the code and the offer link seem to be generic, I think there's a chance it'll work even if you didn't receive it.
