We recently have offloaded / sold loads of old baby stuff as having a clear out. Much has been stored in our loft for 10 years. My husband sold our baby playpen on fb marketplace which comes in its own carry case for £20. We tested putting it up and showed the buyer the item on the doorstep. All happy. Today it's been returned as it "smells musty" and makes the room they had it in smell. I was mortified and immediately gave the guy his money back. Husband has got home and hit the roof that I gave them a refund. He says it's sold as seen and I should have refused. AIBU to 1 - give them an immediate refund 2. Be mighty pissed off with DH for being so completely lacking in human decency?
