Here are all of my items that are now available to buy with Prime! When you click on the "Buy With Prime" button, you'll be directed to the Amazon checkout process, so you can use all methods of payment that you have current there.
But how does my jewelry get to Amazon? I make larger batches of earrings and/or pendants, then ship them all to Amazon to keep for me in their warehouse. Then, when a Prime customer orders from me, Amazon will ship out my jewelry with the same free, fast Prime ship times as everything else Amazon ships.
This is great because I can focus on what I like to do (making jewelry) while Amazon can focus on what they do best (delivering items to customers quickly)!
