Could you not set special delivery as the carrier in you settings when
listing? I am 99% sure you can if that's what you insist on using, in the
last 3 years I have used the tracked 48 service, there is also the 24 hour
service, in that time I have not had a single parcel delayed, lost or
damaged, I can get the exact figure but at any one time I have sent out
upwards of 400 parcels and around 40 in a single day more than once, the
value of individual parcels was upto £500
