Here is more explanationthat I posted on blu bargain side.
You have to have an entirely fresh email account to get it to work. Here is how somebody on blu-ray.com has got it to work. You can actually get two free if you buy 6 items. Instead of using reward25 you should get a warner insider account. http://insiderrewards.warnerbros.com/
On Blu-ray.com people are saying that the code has worked on and off today.

It helps to add items to your cart in specific manner, most expensive items going in first. The system will kick out the "783A42XP" coupon if you have ever used that email address at WBSHOP, even on guest checkout. I assume the best deals will be in multiples of three units, but you can never really tell. Play around with adding items at the end before checkout"
