Unfortunately, most sellers on here will experience something similar at one point or another. Irrespective of the value of the item, it leaves us fuming. The empty box delivery gets more frequent towards Christmas every year. Couriers (or Amazon) often deny it at the time as a matter of routine, but the truth comes out a couple of months later. When sending items like that, I use a stupidly oversized plain (or boring?) box. I mean, it isn't going to fit through the letterbox anyway. Therefore the item is well packaged, but also the courier simply sees a nothing special parcel, with hardly any weight to it. I had a friend who was selling bundles of worthless DVD's, but most were getting 'lost' in transit. He didn't understand it, until I pointed out he was using boxes with pokemon, funko, branding etc..
