For reference, I just sold something on eBay yesterday. I printed a shipping label at around 6:20 this morning, and dropped it off at the post office at around 8:20. It is now 9:08 as of this post. USPS tracking shows that I created the shipping label at 6:22 AM, and the current status is "USPS is in possession of item," as of 8:22 AM. Tracking # 9449009699938001194611 if you want to see for yourself.
