Postie - just to give you some feedback, as you're an insider.
I've had a few cards and parcels never reach their destination. This stops me from using Royal Mail. Otherwise I'd send a lot more things through the post as I'm keen to keep people in work and it's nice to get items through the letterbox from family and friends.
Perhaps Royal Mail need to give out guidelines on how to package things or have a good range of standard packages for different types of cargo. I'm guessing that my items in jiffy bags have looked too attractive to someone along the way, but it's really annoying.
My RW secret santa a few years ago never reached its destination. A gift to a fellow forumite this year also didn't reach its destination.
