... Is the above statement not a wee bit of an exaggeration, Pete? After all, the guy's obviously been "doing his homework" in searching around to establish how to take a small item of jewellery into a foreign country [legitimately] by trying to ascertain the amount of customs duty that might be deemed necessary ... rather than risk breaching Immigration Rules. It's hardly an attempt to obtain a pecuniary advantage (in the form of smuggling), surely.
Quite the reverse, to MY mind!
