Remove Commas From Prices

$1500 seems cheaper than $1,500.

Comma crossed out in $1,500


Prices seem cheaper without commas (e.g., $1499; Coulter, Choi, and Monroe, 2012).

Sure, the written length is shorter. But more importantly, the phonetic size is also shorter:

  • $1,499: One-thousand four-hundred and ninety-nine (10 syllables)
  • $1499: Fourteen ninety-nine (5 syllables)
