These days, is seems the majority of eBay sellers use Click-N-Ship or a similar service through the PayPal checkout. The buyer automatically gets a tracking number and can track his or her package. I routinely ship using USPS Priority but the oversized package surcharge can be a killer (I live on the east coast). To, say, CA, that comes out to about $50 for a lightweight package larger than 12x12x12! The LIGHTER weight the package, the HIGHER the cost! Anyway, I do not normally offer parcel post because people get impatient and I do not want anyone taking their frustrations out on me because THEY chose the slow boat to China. I made an exception and sure enough that is exactly what happened. Because I did not (and could not) automatically send her a tracking number, this buyer opened a dispute with eBay. She never sent me a message asking for a tracking number, she simply opened a dispute. I had given her a flat rate price of $10 for postage and it came out to be around $12.50. Basically I paid for delivery confirmation. The item itself was only $12.39 or so. I MIGHT be able to have the dispute closed by responding with the tracking number but the ornery side of me is balking. I sent her a message through eBay and told her WHEN I sent the package and it could take up to 10 days to get to her. I also asked her to close the dispute and she refused. When I tried to explain to her that she did not automatically get a tracking number because I could not ship out her package through Click-N-Ship, she responded: "enough said on this matter and stop the e-mails". (That was AFTER she told me "communication is everything"). My eBay rep is stellar. I do not care about my rating as much as her implying that I am dishonest.
