Price Per Ball

What it does

Price Per Ball is a comparison tool that displays Amazon golf ball listings organized by cost per individual ball. The site fetches Amazon product data twice daily via an automated Python script running on GitHub Actions, checking for both existing listings and new products. Users can filter results by condition (new or used), brand, and ball count to narrow down options.

Who it is for

Golf enthusiasts looking to save money on bulk golf ball purchases. Players who lose or wear through balls regularly and want to find the lowest per-unit cost across Amazon's inventory. The service appeals to recreational golfers trying to reduce spending without sacrificing quality or brand preference.

Pricing

The site does not show prices.

How it stands out

Price Per Ball takes a focused approach to a narrow problem: making it easier to compare the true cost of golf balls across Amazon listings. Most shoppers calculate price per ball manually or miss cheaper options entirely. The tool automates this calculation and surfaces deals that might otherwise go unnoticed.

The site's architecture uses Cloudflare Pages for hosting and maintains a growing database of product ASINs. The twice-daily update cycle means pricing data stays relatively current. Filters for ball condition, brand, and count give users granular control over results rather than forcing them through a generic product list.

The creator drew inspiration from diskprices.com, which applies similar logic to storage media, demonstrating that this category-specific price comparison model has proven appeal.

What a founder should check

A builder considering a rival should verify three things:

First, understand Amazon's Terms of Service and API policies around data scraping. Price Per Ball appears to pull live data without using Amazon's official API, which carries legal and technical risk. Competitors should clarify what approach Amazon permits and whether enforcement is enforced.

Second, evaluate switching costs and habit formation. Price comparison tools only create value if users visit repeatedly. Without network effects, brand loyalty, or subscription incentives, retention may be weak. Consider how often golfers actually buy balls and whether a free comparison site becomes a destination or a one-time lookup tool.

Third, test whether the per-unit price model actually drives purchasing decisions. Golf ball choice involves brand loyalty, feel, performance preferences, and availability in specific quantities. Price per ball is one factor, but may not be the primary purchase driver. Validate that this metric genuinely influences buying behavior for a large enough segment to sustain the service.
