I just submitted an application but it says it can take four weeks to be approved. When I was younger, my mother used to sell antique and hard to find books on Amazon. Once they went to Prime she didn't like it because in order to qualify for the free shipping your product had to be stored in their warehouse. I don't know if this rule has changed (this was a long time ago) and I don't know what the rules are for Amazon Handmade. If you have product that could potentially be damaged by someone else, having to send your items to an Amazon warehouse is a little discouraging.
I'm interested in hearing peoples experiences with Amazon Handmade and I'll update on my application process later. Thanks!
