Stop testing products 1000 other dropshippers are testing as well. It doesn't work Billy Bub.
You only lost 3k? I've spent 150K+ on my ecom journey/education. Good luck
Best advise I can give you:
Find a product, ask yourself this question 10x: Can I create a unique offer that will be profitable?
If the answer is no, find a product until the answer is yes. If you can't find a product after you've tested a load of them, create your own product or twist of a product, then create the offer.Once you have Product with Great Offer, create a brand.
Dropshipping the way it's taught is dead. You can't copy paste the same offer that 1million dropshippers are doing the same with. It's not sustainable. If you're getting into ecommerce, you need brand building.
Brand building doesn't mean finding a product and slapping a logo on it. Brand building is what I just talked about in 1 and 2. Product + Great Offer + Brand = Now you're doing dropshipping correctly.
Be careful and stop waisting your money. It's not about finding a good product. It's about finding a product YOU can create a great offer with.
PS: What's a great offer? Example: You're selling a diaper. 1000 people are selling the diaper so meta will not let you convert. Yes there is demand already but you have to create your own leverage. How can you sell the diaper and be profitable? Selling a pack of 3 diapers. Oh but now 500 people are doing the same. You still have the same issue. How can you leverage? Sell 3 diapers and a basketball. now 200 people doing the same. Now what? Sell a diaper+basketball+ 1 year subscription to burger king + a pencil, also we call this the Mega Premium Bundle + I slap a professional logo on it with branded content and UGCs. Now only 5 people doing it. Leverage, now you can profit.
