the person that bids on the code needs to know what movie it's from cause disney movie rewards only allows you to use 1 code per movie title per version, so if they already have entered the code u are auctioning off then they can't use it. for instance if you bought 2 chicken little dvds and chicken little on blu-ray, you would only be able to use 1 chicken little dvd code and the chicken little blu-ray code as it's a limit of 1 code per movie per format version.
Sorry i just took out all the digital copies & rewards i found & put them up here. i've never used them so i didn't know so i don't know which movie i took it out of. =(
