Correct me if I’m wrong but signing for a package doesn’t protect you much from being scammed. A person signs for the package before opening it correct? Therefore you don’t know for sure what’s in the box until you get it in the house, open it, then it’s too late. Like someone else on here said, I check the sellers content as best I can and can usually get a sense thru communication if they are on the level. Usually my bullshit alarms go off if not. Personally I have bought and sold dozens of items from all over the world thru eBay etc and have never been ripped off, but certainly understand why people are hesitant to make purchases from strangers. I had a woman in Montreal who wanted to purchase a vintage bicycle from me last year, actually she wanted to buy 2 of them, at $750 each she was terrified of sending me that much money cause she didn’t know me. Anyway she decided to just buy one to start, after she got it delivered she immediately purchases the second one and was over the moon happy. She thanked me and it was a great experience for both of us.
Sending something signed-for or tracked doesn't nix out all potential scams, but it does at least stop anyone from trying to claim it never arrived. It can also protect the buyer, of course, as it stops a dishonest seller from taking the money and then claiming it got lost in the post, and refusing to compensate. Sadly, it's a reality that there are dishonest people in the world, and they will always find some way to try and scam people.
