GameStop makes money on used games

GameStop, according to Wall Street Journal, is making a large part of its profit from sales of used games.

About 42% of GameStop's overall gross profits come from its secondhand business, compared with half that level for new games. "When you consider that most retailers operate on single-digit margins, it's astronomical," said Evan Wilson, an industry analyst with Pacific Crest.

The big contribution to the bottom line is due to the margins on used products -- typically the used games are sold for double what the store gives the former owner (and that payment is in credit toward future purchases). Thus GameStop averages 48% on used product, compared to 20% on new games and a miserable 7% on new consoles.
