Items for sale here and on ebay without remotes....

Clean up day? Heck yes! A guy at work some years ago gave me a huge Klein & Hummel amp and preamp that he had picked up at his neighbors on one of those pick up days. He knew I was an audio guy so he just grabbed them and said here you go. The amp was massive, big meters and everything. The preamp didn't work correctly. The amp sure did.
He was a Science Fiction type so I gave him a big stack of Scifi that I had already read.
Everybody was happy.

I, on the other hand, am always very suspicious of people selling remotes without the associated equipment.  
Talk about your petty theft.  
But seriously, sometimes remotes just crap out. I've had a couple of remotes that had a button or two stop functioning.  If equipment is older, you can't buy a replacement, and the remote is for convenience & not essential; I just toss it out.  
The garage sale catagory is very valid if you also include Estate Sales. The audiophile demographic is skewing older and older, and  when the owners passes on the rest of the family (or the Estate Sale Shop) has no idea "What does this remote go with".
I've also had bad battery experience at least once, so maybe I'll just replace all my batteries in the next few weeks.  Thanks Al.

Stolen stuff gets fenced or pawned quickly. For cash. No grab and run thief is going to take the time to open an E-bay account, tied to a credit card through Paypal, pay to ship an item and wait for payment... seriously...

Interesting response.  However this is AudiogoN, not ebay. 

Jump on ebay if you like to get ripped off.
