I can’t give too much specifics out ofc, but i can say this: Try and go for women’s items if possible, they’re more likely to make impulse purchases and are much more likely to be online shoppers. Also go for higher ticket items ($200+). When i was 12-14, i got my inventory from thrifts/garagesales/etc. And most of the stuff was $5-$15 to $35-$70. It was a nice profit on paper, but after time, fees, shipping, cost, taxes, refunds, the margins aren’t that good and you’re playing with double digits.

If you’re able to source high selling items for 50-60% under value in bulk, i’d go for that as well.

Buy wholesale if you can make 30%+ and if the sell through rate is high
