We have just conducted an amusing test. We sent tracked and regular mail to the US. Both were shipped on the 31st and both were sent to the same address. The regular mail arrived on the 11th and the tracked arrived today, the 19th. I suspected as much but, thanks to a curious American customer we would still be contemplating offering tracked in future. We are now going to save our customers a fortune and tell them not to waste their money on tracked mail. Thought of you guys first and wanted you to know.
