Yes, on the listing page I clicked Make an Offer. It then took me to the page with my address where I put in the offer. I clicked Submit Offer. A window came up to confirm, which I did. Then nothing.
Tried again this morning with the same offer. This time it seemed to go through. Went back to the item listing and a bar at the top said the offer was too low. Within a couple of minutes, that bar was gone. My Marketplace page is still saying "You have not recently placed an offer on any Audiogon listing". So, no record of my offer. If I hadn't seen that brief notice on the listing page, I wouldn't know what happened.
