If it wasn't packed correctly , it would be the sellers fault and a full refund would be in order . ( you would ship it back to him )
If it was packed correctly , it would be the shippers fault and a full refund would still be in order . ( you could keep it and get your refund and the seller would file a claim if shipped insured ) That would be between the two of you .
You and I as a seller can only pack items to a point . The gorillas that throw these packages off trucks and planes with no regards to the contents couldn't care less .
I see that it took 19 days to arrive , did you track it ? Where did it go ?
I went thru an adventure last year with a $1285 set of dies that USPS absolutely destroyed the box and lost half of the dies and bowls . It was tracked and insured . It took 3 times , a full 4 months , full documentation , full before and after pics , multiple conversations before I as the seller was reimbursed . The post office kept the remaining contents of the box . A 2 day priority box took 24 days to arrive , stuck in a blizzard in Illinois .
I don't ship anything over 100 bucks un-insured , and NEVER thru USPS . Pirate Ship is cheaper by far and are on top of complaints and refunds .
As far as the box , pretty easy fix . If the level is good , use it . Let the seller know about the packing issue off the record .
