I recently received a soaking wet, beat up box of 2x Unimogs. Bottom set was beat up bad and torn, top set was wet and sunken in. Contacted Amazon.fr and lodged a return. They sent out replacements free, straight away, and I had to shell out and send the package back. They will credit back the postage ($220) when they receive the return.
Pretty painful but I could not sell the Unimogs in that condition.
I've never received a parcel quite as badly damaged as that (Some Barnes & Noble packages would be pretty close) and it hasn't stopped me from buying other sets. I think it was a freak mishap that they got left out - who knows whose fault it was.
