A common term used in colleges / universities is a "weed out" class. This is a class or subject that is pretty difficult relative to other classes. It's a great way to filter out people who aren't actually interested in a field (or just not smart enough). If you want to be a software engineer, you need to get through Data Structures and Algorithms. If you want to go to med school, you need to pass Organic Chemistry. It's usually the people that truly want to dedicate themselves to these fields that are able to make it through and pursue a career in them. Based on everything I've seen in the last 4 years I think we're seeing a similar phase with selling on Amazon. Back in 2020, anyone with a phone and a car could go to their local Costco, buy all of the swimming pools and make thousands of dollars by listing them online. I know several people who made well over six figures by flipping in demand items like PS5s, graphics cards, chlorine and sports cards. The lockdown era was truly the golden age of reselling. Those days are long gone and most went out of business because they couldn't adapt and learn how to source their own products. This past year has been more of the same. With section 3 deactivations and major brand restrictions, it seems like more sellers than ever are throwing in the towel. This makes me more bullish than ever. A lot of items I'm selling have seen a significant decrease in offer count, which has lead to less price tanking and more money in my pocket. I have no problem admitting that getting started now is a lot harder compared to when I did it in 2021. But for those who are dedicated, we're entering an unprecedented era of low competition on Amazon. It's up to you to put in the work.
