Show HN: ShopSleuth – Get notified when an item is ready to buy

Hi guys,

I recently built a PC for the first time. I found that one of my favorite parts was looking for the best deal for each part. I spent a lot of time lurking on different deal sites and buying the build piece by piece. To save some time, I ended up coding a script to watch items that I was interested in, and notify me when they fell below a certain price. I've saved a fair amount of time and money using it, so I thought this is a tool that some of you could get some use out of too.

Right now it's meant mostly for electronics, but it should work for any item that can be gotten just from the URL. I only have a couple of the big sites at the moment, but have plans to add a lot more.

Let me know if there's anything you all would find helpful to add!

Don't price comparison sites already do this, while pulling in prices from all available shops? How is this better?
