It wouldn't be surprising. I've looked into starting a side business selling some rebranded Ali/Bao items on Amazon, there are loads of niches you could corner. The thinking goes:
> The product is available for $X today, and Amazon takes a $3-5 cut.
> I can buy the product for $X-Z.
> I could sell these products with prime shipping for $X-Y, and make $Z-5-Y on each sale.
Doing that simple math often makes you think you could make a living off the scheme, even after accounting for packaging and inventory fees. If it works for a few months-years, you might double down and get into this situation.
Ultimately, I came away feeling like this is how dropship vendors find new product categories to move into: they wait for somebody to demonstrate that there's a sizable market for a product, then they add that product to their listings and cut out the competition. So you probably have 3-6 months on each successful product, tops.
It's a jungle out there.
