Getting started help

Hello,

I am just currently trying to get my feet wet with being a seller. I bought 10 bars of soap from the dollar store and going to trial with them just so I can understand the process better. Whats the next step from here? Planning on using FBA, do I drop the items off at an amazon store or how does it work getting the items to Amazon. I’d appreciate any help on what to do, the more info the better. Thank you in advance for your help!
