I’ve waited two months for a used book. I don’t know what they’re doing half the time, lol!
I had a customer buy a signed first edition from me and want it sent media mail. What? You are willing to shell out six hundred for a first edition signed (Veronica Lake, autobiography, American edition, some wear on dust jacket) and not spend $10 on priority, insured shipping? At Christmas?
His book did arrive, in good condition thanks to the extra care I put into the packing, but it arrived after New Year.
He called my boss and ranted and raved about how horrible I was that I did not get the book to him by Christmas. My boss pulled the file and read where I had suggested that he pick a quicker method of shipping because it was likely the book would not arrive in time.
He then read the customer the tracking information. I had sent it out the day he bought it, it sat in the distribution center for three weeks.
Media mail, use only when you do not care when it gets to you. :)
