Once again, my tips-
1. Sign up to receive alerts from a reputable and efficient source (this will require a little research on your part).
2. Find out when stock is likely to drop, and at which retailers (again, a good alert source will do this).
3. Be prepared to stay up into the small hours, consider taking time off work if you're really keen.
4. Have the larger stores receiving PS5s bookmarked and accessible. For the best chance, create a link to the product page itself rather than a link to the store front page. This will enable you to skip the first few pages while everyone else is racing through.
5. If possible, do your hunting from a desktop PC with ethernet for optimal stability and speed.
6. Be patient. Don't leave your phone/tablet/PC if a drop is about to happen. You can easily miss it (this happened to me).
7. Be signed up and logged in to the store you're stalking. Make sure all your address and payment details are accurate and ready.
8. Don't give up. If you're persistent and smart, and are willing to put in the work, you'll get one.
Your "alerts" are useless spam, OP. Fighting bots is near impossible. If you really want to try your luck doing it "by hand", you should use a browser plugin like distill. Much faster and more reliable than "alerts".
I got two PS5s from alerts, but I'm in the UK and anecdotally speaking it feels like we got a lot more PS5s than anywhere else.
