Agree with Kraker 100%! Post when you have received your print esecially in the BPE.
That has happened to me when I sent a print and it was never received and the expense was considerable. What I neglected to do was put the value of the print at $0 and say that it was a gift otherwise it will be in the Customs Abyss and never see the light of day!
Also Steven Frizza sent me two postcards from Australia when the first one didn't arrive and the second one never arrived either! Making the resending of a print voluntary instead of mandatory is a good idea too. Most people wouldn't mind but sometimes the cost might be too much and should be an option.
