I have an Etsy business and mail custom furniture UPS ground on a weekly basis. Each store operates differently, the majority add inches to your Lx2Wx2H, they try and charge me a significant increase pushing my package into the oversized dimensions category.
I’m talking a 120 increase per package of totally made up dimensions. I have to argue with them to have them use the actual dimensions. They literally add 2-3inches per side L,W,H.
They give a *** excuse that its Incase the package swells during shipping. No package swells 2-3 inches in all directions but thanks for charging me $120 extra to cover your *** and rip me off
