How do people start selling on eBay?

A friend of mine sells iPhone cases and he says he buys it from China. I mean I want to start because we need the money too and I don't know where to start and I would be really glad if someone really honestly helped me.

My first thought would be to create an ebay account?

So basically are looking to start a business? In addition to selling on ebay, you can also start another business in advertising and marketing if you are a good sales rep. If you are interested I can give you more details. I mean you get $80-$90 commissions.possibly $1000+ weekly.

You have to register an Ebay account.
You may need a paypal account first. (to receive payments)
Anyway it's easy. Quite easy.

Laqualla is right.
But if you just want to start a business, you won't go anywhere.
You've gotta committed to invest your precious money & times as a capital. I highly recommend these as a starting point.
Don't just think, ACT.
