Hey guys so I’m thinking of self publishing a book on Amazon. I wanted to know if any of you guys have done something like that and how it went?

Yeah, I did. They take 55% off the top. So between printing costs, shipping costs and their fee, you need to sell a good amount of books to get ahead. If you're savvy, you can make $0.50 to $1.00 a unit.

I'm not trying to discourage you. Set your expectations appropriately, and put yourself out there! :)

Right, I’m not doing it for the money, so I’m not really concerned about that. Do they charge the author for the shipping and everything? It said on their website they make them to order.

Like as long as I’m breaking even I don’t care

I published my book on lulu.com and had hard copies that I would ship to people. This was 2009, so I'll bet Amazon has a much better system now.

If they are offering to publish your books to order, then it sounds like you'll make more on the bottom line, so that's encouraging!

Either way, hang in there. Once your draft manuscript is done, you just need to stick with it through editing and layout. It is a lot of work, but it's satisfying when people are out there buying a book full of your ideas and creation.

I only have experience with a local publishing house, but I'm generally familiar with Amazon's process. As far as I know, it's free to publish with them and all the fees are taken out of your potential royalties; accordingly, there are higher fees with hard copy sales than with eBook sales. If you're not concerned with making money, then you can price your book low and potentially get more people to read it. There are other online publishers but Amazon has the most intuitive process for beginners.
