What are requirements to sell on Amazon and what’s good about selling there?

Amazon is a great auction site. You basically find the item on their site, you can try this way. First click the “Sell yours here” button, and you basically just put in the condition of the item/how much you want to charge for it. If there have no photos tense free about it., Amazon does the item description/photo stuff if you need. You have to set up an account and give them your direct deposit info so that they can verify your account etc. Then you get automatic deposits every two weeks or so (you can request sooner deposits if you have money in your payments account).

Actually I also know about eBay charges for listings, but Amazon charges off of your profit (the percentage depends on what item, generally around 10–20%), you don’t have to keep re listing your items though, and Amazon keeps it until it sells. They also give you a standard shipping credit (based on how fast the person wants it to be sold-standard is 3.99) which is charged to the customer (sometimes you win/lose on that though with what actual shipping costs)

I think it depends on the items though. Like I sell my textbooks all the time on Amazon, whereas I wouldn’t necessarily say you can sell EVERYTHING on Amazon (like clothes, etc.) but you can sell quite a bit of decent stuff on there. For example, I randomly bought this clock somewhere with nature sounds etc. thinking it had a radio and it didn’t. I think a lot of time passed/lost the receipt etc. so I couldn’t return it to the store. I randomly found it on Amazon one day and decided to list it, not expecting it to be sold but I figured, what’s the risk? Randomly, all of a sudden I received an email that it’d been sold! And I think I basically recouped all that I’d paid for it.

Basically, Amazon’s great, and I highly recommend it compared to eBay (cause you can put something up and not be sure it’s going to sell/what you’re going to get)
