First off, I would like to thank
@BeenBurned for her helpful letter. The buyer accepted the partial refund for the remaining tarts that she didn't use. She also accepted to ship the tarts back at her expense and I didn't have to refund the initial shipping cost. Hence, as BB said, I am out nothing except my time. The items arrived back yesterday and were just how I shipped them out. They smelled exactly like what was listed on the label, so this was definitely a case of buyer's remorse. I am so glad this ended amicably, as this was her first message when she opened the case:
"the wax i ordered was saposed to be orange dreamsickle got nasty old grandma smell instead....how old were these? i used 1/2 of one and wow stinks....nothing like orange or dreamsickle"
Here is her message once I sent over BB's letter:
"I have shipped the wax back it should arrive by Monday 3/12 the tracking info is
xxxxxx usps i will be awaiting the refund...thanks for understanding"
It sounded like two different people based on how the messages were worded. Either way, I am glad it's done and over with. I've kindly asked her to close the case when I sent the refund, but of course, crickets on her end... What should I do next? Do I call eBay and have them close the case or just let it time out? What about the defect...is there any way to get that removed from my seller's account?
