I haven't posted one of these in a while, but for your entertainment value:
from the buyer - Got the card and the slab case was busted and cracked! Please Lmk what you plan on doing
my response - please send the card back to (my address) and I will refund you in full upon receipt.
his response - Im not sending back until I'm refunded, or you can do a paypal refund so I can keep the card
my response - i'm sorry, but it doesn't work that way, please go into your ebay and request a return, and you can print a label to return the card.
Keep in mind - I double-bag all my slabs, so while it's feasible the slab got cracked due to USPS's shoddy handling - this is the first time I've had one crack in transit in a long time.
