Since your first question was answered, I'll share the experience I just had with applying my Kingdom Hearts promotional credit.
I e-mailed them about applying it to Uncharted 2. They basically did it, but rather than simply take $10 off the price, they lowered the price of the game from $57 to $47. I'm not going to contest it, but it did bring my ECA discount down by a dollar. So my only experience getting them to apply it thus far has been successful, and without hassle.
