Would just go with AliExpress and do your research.
For shoes buy on Amazon.
For phones but on AliExpress.
For clothes but locally.
Anything that you drop for being a idiot buy locally as international may not have warranty.
For selling as a drop shipper is competitive, before drop shipping only needed a 16 year old clicking on share referral links, and using that money to buy the a product and sell it, then use their money to buy it that you never had as a middle man.
Now it's saturated(but you're not listening) because if you were you'd have built your herminapolich brand doing exactly this.
Anyways AliExpress is the no brainer it's Alibaba direct from china.
My last scam on Alibaba was 2011 for not understanding a iPhone for $120 is not real where all the touch inputs were scripted from a Nokia, god it kept making clown photos and only had 2 ring tones that could not be deleted.
You can still experience this but with research no.
