The only cost might be UPS were already paid and you'd lose $120 on throwing that label in the dustbin.
A label is fully refundable up until the time the UPS driver scans the package. There is no excuse for not offering full refunds as promised up until the time the package is picked up.
Not disagreeing with you at all, I think they should offer refunds up until they ship the customers particular order however you did agree to their terms which stated no refunds once they start shipping and obviously they started shipping...
BFL started "shipping" in April, and used that as reason to deny refunds in October :-)
