The last step is to ship the item. If you use PayPal, you will get an email confirming that the winner has paid, or if you are getting paid another method, you might get a check in the mail. Make sure you package your item well, after all, you might not make any money if the item gets broken on the way. You might want to consider tracking. If you have a tracking number, either through UPS or Federal Express of USPS, then you can provide that the other party received the item, otherwise you will not be able to. If you are selling a cheap item, it might not be worth it. USPS media mail is a cheap way to ship books or DVDs and similar items; it comes with tracking information, although first class mail, which is more expensive doesn't. Ultimately, it is up to you. If you don't use tracking, then ship very quickly. One time I got busy and it took a few days to ship an item. The customer emailed me and asked where the item was. I sent an email back and shipped the item. He submitted a claim against me on PayPal because I didn't have a tracking number, he got his money back and the item. He later claimed that he didn't get the email because he forgot which one he had signed on. He refused to pay for the item and felt justified because I was late in shipping the item. I could do nothing, even though he sent an email through EBay that he received the item.
People are jerks, and that is why I am going to give you a piece of advice which might be a little controversial. Customarily, once a person has paid and you ship the item, you give feedback to the buyer. I would wait until they have given you feedback or they have had their item for a few weeks. The reason is, well, people are jerks, not everyone, but anyone who has worked in retail can tell you, there are enough of them it makes it seem like a lot of people are jerks. Your only defense if the feedback. If you have honestly described your product and have taken accurate pictures, then there is no reason anyone would complain about you. Yet they will, and they will leave you bad feedback unless you haven't given them feedback and they are afraid to leave you bad feedback and give retaliation. When you do give feedback, only give positive feedback unless there is a very serious reason not to.
