Should dealers be able to......

I agree with Sdcampbell. Anyone that builds an e-mail list from A-gon members (not easy since the actual e-mail is hidden until you get a reply from someone) and then uses that e-mail to send "this month's specials", or other spam, in my opinion is completely wrong. However, if a dealer reads comments in the forums and believes they have some pertinent information, that would otherwise come off as advertising in the forums, then I agree with SD that this is more showing initiative than being annoying. I also agree that if a user requested not to be contacted, or simply didn't reply to the e-mail, the dealer should take the hint and not e-mail that person again. I've only had one person e-mail me to tell me about a particular product. I wound up trying it, it didn't work for me, and was very easily returned for a full refund minus the shipping. Although I didn't care for this particular product, this person's business practice was such that I would do business with them again.

It is very simple anyway:
Weather you or someone else accept the offer or not before it's being advertised on the web. Sometimes it happens to find it reasonable and go for it and that's for you do decide. The main thing is not to think that you're saving him/her $2 ad fee:)
You're right being not the only one. I get it from time to time as well and deside myself seing nothing wrong in this situation.

I would prefer not to recieve email unless I solicit it. I don't care for the medium,though I recognize it has it's place.

If one dealer has sent more than one email, just block the address using your email application.

IMO yes: dealers should be able to email Audiogon members. I receive them regularly & find them to run the full range from very worthwhile to useless. Overall these communications have provided some good information that I'd much rather be with, than without. The mails that I don't find useful - well that's what the delete key is for.
If you find yourself on a monthly newsletter mailing list that you'd rather not receive, simply reply back you want off the list. They are required to delist at your direction.
