I don't agree that's simple, nor (strictly) price discrimination.
The most obvious added value is faster delivery: ship today instead of in X days/weeks when the auction ends.
It also has weird value if you for some reason believe the BIN price is undervaluing the item, i.e. you can short-circuit the auction before anyone else realises.
