u/Cheap-Will-1467

I been reselling on and off for about 2 years and I never did crazy numbers. Im guessing my problem is that i only really listed stuff on limited marketplaces: Facebook or Depop (im now banned from depop) and another thing is the long ass shipping time so it ends up taking 2 - 3 weeks for me to get a small batch of products just to test out. When ever I would buy a product that looks decent to resell, it moves slow or it doesn’t sell at all. Im now ready to go all on this shi, I’m just wondering how to find a good designer, electronics, etc. product to resell before it’s known by everyone and their mom

got this g37 back in November, finally got tint today and it’s looking pretty good in my opinion but what should I do to it next? I’m looking for somewhat cheap mods/ upgrades because I just spent hella money on repairs
