How/where do i find things very cheaply, i can then sell for more?

[An Infinity Of Little Hours]

Thrift store tbh on a small level 

Don't try to run these scams - like Amazon scams and shit

This girl I know would buy like 10,000 sweaters and resell them for $2 more on Amazon and all this shit 

but sometimes things would get screwed up and she'd be stuck with 80,000 fox sweaters or like some weirdass 500 ninja turtle socks and shit 

honestly... just sell panties online. but say you're a girl. wear each one for about three days then sell for $50
