I have gotten 1 empty envelope cut with scissors and stuff taken (actually filed a police report on that one)
1 envelope like cut with scissors (it was like someone opened it up to look and put all contents back)
I thought taking a break from trading during the holidays would be wise. But I think the post office doesn't have enough help and some of the help they have is horrible in my opinion. Of course they have nice workers also but..
I also have a lack of time, currently however everyone is at the mercy of the postal services.
If it's a high value you should insure it. I only do lower value PWE so ..
I can understand your frustrations
