Is a offer of -20 percent on an OBO ad insulting?


I made a offer 20% below the sellers asking price on a Krell last night. The seller emailed that I shouldn't waste his time with such a ridiculous offer and that he was blocking me from his email list. Was I out of line?

I agree with Herman. While I typically offer about 90%, I don't think an 80% offer is deserves that type of response. A simple "your offer is to low would have been sufficient." Often with low ball offers I just send back a counter offer and to my surprise many times they will move up. I am surprised by people being insulted. Your selling an object; a thing. We are all looking for bargains that's why we buy and trade on audiogon. If not we'd be buying retail.

Also who determines going rate? As an example, I have looke at the prices of a Pass X250 (I own the x150). Look how many are on sale here and most of the going rate is around $3500 to $4000. None of them have sold. There is one for $3200 a 20% discount off of the "going" rate and it has not sold yet. I have not made any offers since I am not ready to purchase, but let's face it, the Pass x250 is probably worth in the low $3,000. Yet I'm sure many will be offended with a $3200 offer.

Just my thoughts,

I agree with Herman too. If you sell obo it's just that. You have to expect offers at that price(20% off).Especially in the audio market right now which is a buyer's market. If he has time to insult you he has time to simply say no. I think he's being a jerk. No loss being "blocked" from that. It's a blessing.

I remain,
Thanks for the conformation folks. I must say my ears were burning after I received that response and that I wouldn't what to deal with that seller. Also, I am ready to buy and would like to try a Krell.

It doesn't take alot to be polite. OBO is just that. Your offer may not be his best, but if you're a serious buyer, if he wasn't willing to accept an offer then he should have put firm or courteously declined and counter offered. Many times I've bought and sold equipment right here for +/- 20% off OBO and in the end both of us were happy to have been able to put together a deal. This guy is just too proud, too stupid, or just a putz!!!
As a frequent seller and buyer here I agree with the posters that asking 20% off a OBO is probably low but with in reason. I always acknowledge all offers as a courtesy and if the price is lower than I will accept I ask for a counter offer or give them my bottom line selling price. I avoid ads that state low ballers will be ignored(what is a low offer to the seller may not be one to the buyer) and ads that say don't ask me again about condition ect. If the seller states the price is firm and I want to purchase this item I pay the asking price, if the price is a little on the high side I may ask to include the shipping or even split it.
