Help with shipping. Ebay calculated price looks way too low

Question

Hi, I want to sell an old iMac computer. In the package it will weigh about 40 lbs and the box will be 30" X 30" X 30" after all the bubble wrap and paper. The eBay shipping calculator comes up with

USPS Priority Mail

1 to 4 business days1 - 4 business days

Max. 70 poundsMax. 70 lb

$11.70 - $26.90

There is no way that can be correct. When I look up USPS Ground Advantage it comes out between $93 and $246 depending on how far it has to go. I don't want to just flat charge $246 but I can't get the eBay calculator to estimate anything close to what the cart from the USPS indicates.

Any help is appreciated.

Your package is too big for USPS - the dimensions exceed 130 inches

Combined length and girth can't exceed 130 inches for USPS

Girth = 30x4 sides = 120 + 30 length = 150 inches

So one of the quirks is that eBay is showing you flat rate pricing, in case your item fit into a flat rate box....

If that is the size box you must use to ship safely, you'll need to look at UPS or Fedex.

(You can't ship Ground Advantage either. )
