Ah good, so they changed it. When I received the M-122, I was expected to pay return shipping to Canada in order to get the refund.
Policy has been that way since at least 2012.
From eBay support, when I opened the case:
"Hi XXXXXXXXXX,
We let the seller know the item wasn't as described.
The seller has offered you a full refund for the purchase price plus original shipping if you return the item. To get your refund, ship the item back to the seller.
You will need to cover the cost of returning the item. Make sure you ship the item by Jan 27, 2014.
Refund information:
Once the item is delivered to the seller, you will receive a full refund of $78.00.The refund will include the purchase price plus original shipping.
You can view the details of this case and learn what you need to do to ship the item back in the Resolution Center."
