Yes, I'm aware of that, but in this case the stated amount in the listing was the same as we put in the shipping label so the two weights and measurements matched. But ebay/USPS charged the customer $7 while charging us/her $10.42. The actual weight came in at 1lb 12oz so that is what we changed it to before actually buying the label. That billed us at $8.82.
We played around a bit with the box size to see if anything came close to the $7 USPS priority rate, but 8 x 8 x 8, 7 x7 x7, 10 x 10 x 10 all at 1 lb 12 oz was about the same, and nothing close to $7.
Personally I was surprised any USPS priority mail rate from California to Oregon would be as low as $7 for a 1 lb 12oz package. I would expect the higher price, but just don't know how ebay calculated the lower price
