When I sell I send the auction winner an invoice.And when I get paid, I get an email notice that says "you just received a payment from so and so" Whoever won the auction in other words. Then I log onto paypal and see if the $$$ is actually there. If it is then I see what his address is and send the package with a copy of the invoice inside. To print shipping labels you need to open an account with UPS or USPS and you can print your shipping lable with a bar code already on it. I just drop mine off at the local postal annex and they weigh it and charge for shipping then. Sometimes I will prepackage and weigh it at the annex so I know how much to charge for shipping. You can inflate the shipping if you like but sometimes that will affect the amount of bidders you'll get. I hope this helps.
When you package, make sure the item doesnt shift and slide in the box. Cut up cardboard and newspaper balls work good. Lots of clear packaging tape to make the package durable.
Most of all be honest. Dont try to sugarcoat how the part is. Good clear pics and tell the truth.
