I took inspiration from diskprices.com, but applied it to my golfing hobby.

For someone who can't always keep it in the fairway, golf balls can get rather expensive, so I decided to build a way for me to view Amazon listings by how much they cost per ball in the hopes of finding some good deals. Hence the name of the website.

The site is hosted on Cloudflare pages and I use Github actions to trigger a python script that fetches and checks the prices. It runs twice a day. If the script encounters any new ASINs, it stores them for future checks, so the list of golf balls being price checked should keep growing over time. Changes are then pushed to Cloudflare pages.

There can sometimes be some pricing oddities when the product title says one count, but the unit count being returned from Amazon is another number, so I'm trying to add some checks to help accommodate for that. Right now, I just have some manual overrides for certain ASINs, but I'm looking to improve on it in the future.

The frontend is just some basic HTML, CSS and JavaScript.

Listings on Amazon can be inconsistent sometimes because, for example, product titles will say used balls, but the seller lists them as new. I added some filters to that allow you to exclude used/recycled balls, plastic golf balls, etc... You can also filter by brand.

Give it a spin and let me know if you run into any issues or have any feature ideas to make it more useful.
