Well, I sent them an email and a link to this thread and suggested $100.00 as a refund, and asked them to suggest what they thought would be right. I guess this place really carries weight these days because this is what they wrote back:
Hello Ken, we have sent you $125.00 refund. We are a small Mom and Pop store that sells many things. We have been selling on Ebay for over 10 years and since retiring 2 years ago, we have been doing it full time.
I thought I had described the item correctly, but this is certainly not my area of expertise and I respect your opinion.
We want our customers to be happy with their purchase and will bend over backwards to make it so. Integrity is the most important trait a person can have.
Thank you for giving us the opportunity to make this right.
Kindest regards,
- sweetwater_general_store
All I could think of is "what would Norm do?"

So I thanked them and explained that integrity is something we value here at Boomboxery also, and sent $50.00 of it back. I told them that I only suggested $100.00 and was expecting them to counter with a lower figure. That was based of course, on my belief that they honestly represented the box as they found it.
So thanks, everyone. I came this close to donating the $50.00 to Boomboxery, but stopped at the last minute. All I could think about was that they were retired.
Thank you for all the opinions and everyone chiming in. Got a refund so I guess I better move this one to the front of the line and spiffy it up for pictures. Got some work to do.
