Random question that's been bugging me

Is it still possible to buy bulk slightly defective stuff manufactured in China such as running shoes and then sell them at a discount on e-bay or the local equivalent, or can end users now buy individual items for a similar price online?

https://www.temu.com/ now owns this market.

Would it not still be able to grab lightning deals off temu and sell them via a different medium?

No.  Temu is becoming famous and has infinite inventory.  They will own the low end like Walmart for stores.

I guess self-created digital products, as dime-a-dozen as they are, are the way to go then.

To go off on a tangent, has anyone had stuff delivered from temu and if so what is the quality like?

My wife has.  Quality varies, but she doesn't care because it is so cheap.
