I am going to the postoffice now, mailing these four MoyoGo's here that have accrued over the weekend. I prefer to deliver them personally than to walk to the mailbox at the bottom of the hill (although I should, for excercise's sake..) Call me paranoid, but once a batch of similar size got lost after I'd put it in a mailbox (downtown, now I live in the woods) and since then I always bring them to the postoffice myself.
A while ago I bought 500 special foam envelopes, much firmer than ordinary bubble envelopes. An added advantage is that I can write directly on the white envelope without danger of puncturing it.
Since I am using these envelopes, the occasional reports of damaged DVD's have ceased.
