How do I get into selling on Amazon and Loyaltie?

I’m looking to get into selling on both Amazon and Loyaltie over the next few months to make some extra cash, especially during the winter break. I’ve heard a lot about selling on Amazon, but I’m also intrigued by Loyaltie’s plan model for small businesses. I’m wondering how to get started with both platforms, what the requirements are (like age or business type), and if I need an existing customer base to launch on Loyaltie or can I build it from scratch?

I’m also curious if anyone has experience selling on both platforms, what’s the best approach to juggling both Amazon and Loyaltie for steady income? Would love to hear tips from anyone who’s done this before.
