I am three months into the reselling business. I am still learning and building my business. I am working part-time but want to grow to full-time eventually. I was wondering when you should invest in an eBay store. I've also looked into Vendoo and listed five items for free on Poshmark through Vendoo. So many decisions, I just don't want to lose money and get in over my head. Any advice or what you have experienced just starting??
