I would disregard the "FTID" method because it relies on the reps not doing their jobs at all, and for 2k+ item you can bet your ass they will do a pretty deep investigation, and if they catch you, you'll have no plausible deniability at all.  Better to go wrong item recieved method or DNA if no OTP is needed, shoot probably even damaged item method if you can photoshop pretty good.
