Why do you charge $3 for signature, when it costs $1? I certainly wouldn't pay $3 for the signature option on C&S.Why do you not include it in the item price or handling cost if you don't offer any other option?

NO, it does not cost dollar, C&S parcel with signature costs $3.15 on top of the postage, or $1.55 for tracking only.  And I enter it as registered (which it is) and normally it comes up as a total including the $3.15.  I also get insurance, which comes on top of that, but I pay that out of my pocket.

Normally, the total quoted price is pretty spot on, but I just got another parcel that came up wrong, and this time I am out of pocket $5.50!!!   Not happy.
