Can't help but think this most times when I read a complaint from a buyer that's from a very well respected vendor or the like. "The vendor marked as shipped on this date but never actually got it" - probably seized by customs or something which really isn't the vendors fault in my opinion. Or something ridiculous like they only received half of the order - most vendors are not that stupid. Either that or the vendors just make many many mistakes which I find unlikely. Anyway interesting to hear what you guys think - is there really people out there stupid enough to scam vendors? I reckon it happens more than you would think.
If the order is seized by customs it is absolutely the vendors fault. They are the ones responsible for packaging the item(s) in a way they cannot be detected by customs. Thats the whole point of the "stealth" rating category.
