Thats the worst that can happen, especially decepticon jets, with all their pointy bits etc, their bound to cause damage/dents to the windows...
This time around, no windows was damaged, two boxes were CRUSHED and some boxes had slits/cuts, he placed the mib jetfire and megatron at the TOP, the combined weight of these (fairly heavy) plus rolled up newspapers placed ALOT of pressure on the autobot cars and dinobot boxes which were at the bottom. I have been trying to fix the crushed/deformed boxes by putting dvds cartridges inside to form a temporary stable mould to get it back to its original shape and remove the dents...
The second crap packaging experience I've had, is when my MIB hardhead got shipped in a shoebox from england. I told the seller his an idiot and should give me a partial refund for such idiocy especially when I even accepted to cover his paypal fees, he said I was a lying prick.
