I believe customer service is the key to success for any business. I attempt to make every exchange and sale in eBay a win-win for the buyer or seller and myself.
When possible I ship for free. Otherwise I ship according to the dropshipper I am working with at the time. If I am selling one of my personal item, I use the USPS and PayPal shipping labels.
