Do you collect Disney movie rewards points? I love them now. If you buy new Disney DVDs there are reward points inside the case (usually worth at least 100 points). You collect and enter them here (no credit card needed to collect them).
There are rewards at all point levels but the best for us is starting at 550 points. We were able to get a Disney DVD Free by redeeming our points.
We rarely buy new Disney DVDs but by being willing to wait, I am able to find quite a few free codes.
