Pricing
Remove Commas From Prices
$1500 seems cheaper than $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)
