Hello, curiously enough I was developing a bot for a similar task yesterday: tech deals that expired in milliseconds because of the very limited quantity (1-10 units). I succeeded in getting some of them, not every one of them, unfortunately. It is very difficult and requires a lot of studies and trials. So, I'm interested in helping you in this project, if you are interested in working with me, let me know and we can discuss the details (which websites for example).
