Quickly jumping in here cuz I've been obsessed with tracking down old Super Takumars lately. Honestly, the manual refresh game is the worst way to live. I'm no expert but I've been experimenting with a few ways to automate this. I think I read somewhere that eBay changed their API recently which broke some of the older tools. Not 100% sure on the technical side, but I noticed some extensions get laggy if you have too many active searches. IIRC, some people use RSS feeds but that feels a bit old school and might not be fast enough for a weekend shoot. Here is what I have gathered so far in my journey:

• Some tools run in the background and use more RAM than youd expect, so watch your browser speed.
• I heard PriceDropCatch is decent for getting those alerts without too much setup, though I'm still testing it myself to see how fast the push notifications actually are.
• You might want to look into browser-based scripts if you are tech-savvy, though that might be overkill.
• Check if the extension supports Buy It Now specifically versus auctions since the logic is different. Anyway, I'm still learning the ropes but it definitely beats staring at a screen all day. Hope you find the gear you need in time for your shoot! Lemme know if you find something better tho.

TIL! Thanks for sharing

I have been tracking vintage glass for years and my current setup finally solved the frustration! I used to lose out constantly, but switching to a dedicated tracker changed my workflow. It is fantastic! 1. Enable desktop notifications for maximum speed.

• Sync the extension with your active browser profile. I highly recommend using Capital One Shopping because it isnt hard to use and it is truly amazing for catching those price drops instantly!
