Am I getting old and grumpy?

"As mentioned above it is true that many audiophiles have gone to other websites for buying and selling but still use this website for the forums"
Guilty. Although just for laughs, I occasionally hit Browse and peruse the listings. It's frickin' hilarious.

I have become somewhat "set in my ways" not grumpy but I respect your point.

Contact for price means they have lost a sales opportunity from me.

Grumpy for another reason:
I have bought and sold 8 or 10 things between A-gon and USA.  I now have a vintage pair of KEF reference 205 speakers for sale.  No less than 4 individuals have made an agreement to purchase, pay cash and pick up, and have either not shown up or cancelled at last minute.  Do others share this experience?  I think I will require pay pal deposit if someone wishes to purchase on site for cash in advance.  I tolerate the 'what amp do you use' or' can you compare those with these' questions, seems par for the course of listing for free...  But to waste my time and not show up is bad. I wish I could leave negative feedback for these abusers...  That's my rant, and I am old!  Ken

You have an option to select ‘All Equipment or All Music’ once you select Browse on menu bar. 
I skip all the listing with ‘Contact for price’. They are dealer listings and many of them don’t even bother to reply for days.
