Resale prices for these DVD's in new condition increased 48% after Avengers came out and unit sales jumped 27% too.
Reason for the Big IncreasesMore than 17 million people saw The Avengers during its opening weekend and it grossed a record setting $207 million in three days. After seeing the new movie, many of these people decided to buy the DVD's for the individual characters as well, which increased demand.
Supply wasn't able to increase as quickly as demand did so prices increased to compensate - Economics 101.
