Quick reply while I've got a sec! I went through this exact same thing last year while building my setup and man, it was a total roller coaster! I was so incredibly hyped to find a deal that I almost fell for a massive trap. You gotta be super careful with those third-party sellers that suddenly appear on the Canadian site when prices dip. I saw this legendary price drop once and I was ready to celebrate!! But then I noticed the seller had zero ratings and was basically a ghost. It was such a close call! My biggest tip is to never, ever ignore the sold by info even when you are in a rush to beat the bots. Those fake listings are everywhere lately and they look so real when you're excited. Just keep your guard up because a cheap card isnt worth the headache!

If Keepa is lagging on those lightning deals, its usually because their server-side scraping frequency gets throttled during high traffic. For a 4080 Super, you basically need something that monitors the client side. I have had success using Distill Web Monitor because it lets you select the specific CSS selector or XPath for the price element. It runs as a browser extension, so it checks the page directly from your connection. You could also try this price alert tool to fill the gaps when the big names miss a sudden drop. Just be careful with setting the refresh interval too low or you will trigger a captcha loop. A 30-second window is usually the sweet spot for high-demand hardware. Honestly, building in Toronto can be tricky with stock levels, but using a local monitor should give you the edge you need before next week.
