Does anyone have experience with Amazon FBA?

Good morning,

My partner and I are planning to start with Amazon FBA. We are both M18 and F22 and still have 1.5 years of training left. Our plan is to apply for everything we need in the 1.5 years, i.e. a business with the appropriate legal form (we were thinking of a Gbr), ROI number, etc. etc. We will save up a start-up capital of around €3,000-5,000 over the next 1.5 years and will spend this time extensively researching the topic so that we know everything about it. Now my question: does anyone of you have experience in this area or have any tips that you definitely need to follow, or just tips that you don't get otherwise? 🙂

Thank you in advance, have a nice week!
