So I've been eyeing the Sony 24-105mm f4 lens for months now but I just can't justify the $1,100 price tag right now. My budget is strictly $850 or lower because I'm saving up for a trip to Japan in late June and I really need to have it by then. I did a bit of searching and found sites like Honey and CamelCamelCamel but honestly they aren't doing it for me. Camel is great for Amazon but a lot of times the best camera deals are actually on B&H or even Adorama and I haven't found a way to track those easily without checking manually every morning like a crazy person. Honey just keeps giving me coupons that don't actually work at checkout which is super annoying and kind of a waste of time.

Ideally I want something that:

• sends an actual push notification to my phone or an email the second the price drops
• lets me track specific URLs from different retailers not just Amazon
• is free or at least very cheap because well I'm trying to save money here lol
• doesn't sell my data to every telemarketer on the planet

Is there like a specific app or a browser extension that actually works for this kind of thing? I tried setting up Google Alerts but it just gives me random news articles instead of actual price changes. I'm getting kind of desperate because I dont want to miss the window for shipping before I leave. Any ideas?
