This same thing happened to me about 5 weeks ago then I started a thread here about a month ago " Recieving annoying Emails when selling"
I was blasted by a couple members for some of my comments but they were helpful because I did learn something..
1. "obo" opens the door for trouble and potential endless questions and lowball offers.
2. A history of the item helps the potential buyer make a decision and reduces amount of email questions.
3. The condition of the unit should be described in detail.
4. If you don't have at least one good picture ( not a fuzzy blurr ) , it's like asking the "potential buyer" to buy blindly and you may have several requests to send pics.
5. When the buyer seems serious, most the time I give them a phone number where they can contact me.
6. A link provided with full specs. and/or a good review of the item is also helpful. It reduces the amount of trigger happy shoppers who may find from the review that the item won't meet their needs after all.
7. The hassles of calculating shipping costs to several potential buyers is totaly eliminated by a simple phrase,
" Free shipping". Add that cost into your price.
8. Last but not least if you want a certain price for the item clearly state " FIRM " in the add.
Most of you folks already know this stuff but maybe this may help someone.
I admit that I backed out on a deal about a year ago when I found out more specifications about the item. I shouldn't have jumped the gun. It's possible that if all the info above was included in the add I wouldn't have offered to buy in the first place.
Have a good Thanksgiving!
