Haven't sold any. Sent out a catalogue sheet to all the big box stores and any that were seriously interested wanted to see a sample. Factories quoted me 30-45K just to start. It's definitely on the back-burner, though.
For best cooling you want to use a mix of Ice and cold water, with a ton of salt. This lets the water temp drop below freezing, and makes better contact with the cans/bottles, transferring heat away from them faster.
It makes a pretty big difference, especially when you've got a bunch of warm beer / wine and want to get it to a drinkable temperature as fast as possible.
