Why can I not put in dimensions of my package when shipping using USPS Parcel Select when listing thru Auctiva?
Example: I just shipped a eBay sale Box that measured 21 x 18 x 14", which 2 qualifies for the 84" max under USPS max. measurements for a Regular Sized Box.
When I listed it, I put in an extra 2 pounds (13lbs total), but could not put in measurements.
The box ended up weighing 11 lbs and once I calculated the pricing thru Ebay shipping labels, it came out costing me nearly an extra $3.00 on postage. Grrrrr
This is the second time this has happened to me, that I've had to pay out of my own pocket because of the weights not being figured correctly.
Can you tell me why?
