• Price against the market

  What comparable seats are going for right now, all-in. The bigger the gap in your favour, the higher the score.

• Row quality

  How close the row sits to the stage for this kind of room.

• Angle to the stage

  Whether you are looking at the show or across it.

• How much of the price is fees

  Two seats at the same all-in price are not equal if one is mostly fees.

• Scarcity

  A small nudge when a seat is the last of its kind on sale.

Prices we compare against are all-in, so fees can never hide inside a "good deal".
