Hi all, Just sold my first book on half.com. Printed the packing slip and then went to print a shipping label. Problem is, I don't know how much my package weighs. My question is, do you have to print a shipping label through half.com, or can I just take my package to the local post office and have them set it up for me? Will I still be reimbursed for the set shipping fee from half.com if I do this? I searched the half.com website, but it feels like they are pushing the print-it-yourself labels, so I have no idea if that's the only way to do it or not. I also want to make sure I'm saving money, so I don't want to overcalculate the weight of my package. Thanks so much!
