I kept missing good Pokemon card deals on eBay, so I built a free alert tool that watches eBay for me
I got back into Pokemon this year after a 25 year break and decided to collect all the base set unlimited holos in NM. Pretty fast I was refreshing the same eBay searches all day long and still missing the good ones.
As a developer I knew there must be a better way, I couldn't find any tool to help me do that so I built a little app for myself. You add the cards you're hunting, set your max price, condition or grade, and it pings when a matching listing goes up.
It also flags auctions near the end that are still under your price, which is where I've found my best deals.
It's called ChaseBoard and it's free to use: getchaseboard.com (eBay links are affiliate links, costs you nothing and keeps the app running).
I'm still building it, so if there's something you wish it did better, tell me and I'll probably add it.
Would be happy to hear what you guys think about it
