how to easily sell items (like 1 or 2) on amazon?

I'm not looking to make a business out of this, I just want to sell something (a ps3 controller) and want to know the best way to do this. I also have a few other things that I was going to sell... maybe I could do it now, but again, nothing big.

My main question for now is should I ship myself or send it to amazon?


I may have a few more questions so please check back!
via...ups? how do I do this? just bring the item to the post office......?
ok so find a ups and bring everything in. package it myself, right? and do I need a bar code or anything?

Iv sold a few easy items on Amazon before. I always just shipped it myself via UPS with the smallest box I could find doing standard delivery. Never had any complaints.

Via --by a route that touches or passes through
UPS --www.ups.com/ go here and find one closest to your location. Walk in with the controller and they will have everything you need. (oh and also the address to where its being shipped)
