Sold three books using USPS Media Mail with calculated shipping. For two of them, it would not give option to change weight/dimensions when paying shipping label. Instead of the usual change dimensions box, there was a long message that started with something like "Maximum weight is 70 pounds and 1080 inches..."
Whatever price the seller was charged based on my initial weight estimates, that's the amount I had to pay. No option to adjust. Luckily, I did not underestimate the weight. Anyone know how to avoid this for future listings?
