A Hacker News user has created Price Per Ball, a tool that sorts Amazon golf ball listings by price per ball to help golfers find better deals. Inspired by diskprices.com, the site uses Cloudflare Pages and GitHub Actions to fetch prices twice daily, storing new ASINs for future checks.

The developer built the site using basic HTML, CSS, and JavaScript, with a Python script handling price scraping. The tool addresses a common frustration for golfers who frequently lose balls and need to find cost-effective options. Current challenges include inconsistent product listings where titles and unit counts don't match, requiring manual overrides for certain ASINs.

Users can filter listings by brand, exclude used/recycled balls, and remove plastic practice balls from results. The site already shows significant price variations, with Nitro Crossfire balls at $0.62 per ball compared to premium options like Titleist AVX at $1.10 per ball. The developer plans to improve the ASIN matching system and welcomes feature suggestions from the community.
