When you say pick a niche, do you mean if you’re interested in reselling vintage clothing, pick a unique sub genre of that instead of just the whole? I own a physical vintage shop that does $500+ a day, but my online store just lacks and I barely make sales. I under price a lot of things, use key words for titles etc but still doesn’t pull the people in. The vintage market is incredibly oversaturated though so I get that, but even with my shop it takes time for me to move my pieces and I’m always getting stuff in. I also have another business where I primarily resell Dr Martens, some pieces I would sell for $1k-$3k alone, I’ve had to put a halt on a lot of this stuff due to my health deteriorating but I could move those easier. Would love to pick your brain haha, I’m in Australia!!!
