What’s the most reliable method to catch PS5 restocks today?

[Mason68]

I've been trying to buy a PS5 for my nephew's birthday next month for weeks now, following various stock alert accounts and checking retailer sites daily, but every time I get a notification and click the link, they're already sold out within minutes. The process is incredibly frustrating, and I'm starting to worry I won't be able to get one in time without resorting to paying a huge markup from a reseller. For those who have successfully purchased a console recently, what is the most reliable method for catching a PS5 restock right now? Are there specific days or times that are better for certain retailers, and do you have better luck using the mobile app versus the website, or is it mostly just being pre-logged in and ready with payment details the second an alert drops?
