First let me open stating that I know it is just a box, and there are many opinions on boxes (keep, toss, burn, sell what have you). I share this story not looking for advice on how to deal with the seller or to be told the box dosen't matter or learn how you manage your boxes, but to find solace in the sharing of your shipping stories that are jaw dropping astonishing in positive, amusing, tragic ways.
A few days ago, I made an online purchase of a Post War Accessory that was complete with original box. This listing would indicate the seller did their research or seems to know their Lionel trains well. Seller shared tracking information and I was excited to get notified that it was delivered today. I got home and saw it on my front porch and I just became exasperated. On my front porch was the nearly pristine original postwar accessory box used as the exterior shipping box! Of course they went overboard on the clear packing tape. In a corner, the tape had started to come undone and it is very apparent that removing the tape would pull up the fibers of the box and the printing. Quite maddening if you ask me!
