Feel free to correct me if I'm overlooking something...but if you offer within 10 or 15 percent buy it now price....and the seller doesn't even respond they should lock his auction and keep charging for the listing. They can use settings to screen bad offers. Use them or entertain all bids. I'm tired of offering 225 or whatever on a coin which locks up 225 of my budgeted money regardless if there are other examples I am looking at. I have to honor that offer even if I pull the trigger on a comparable pc later. Waiting 24 hrs to do nothing just annoys me. Just sayin...
!00% agreement here! I try to respond to all my ebay offers within 3 hours, granted I don't always get to it within that time if I'm at work or something but even then I could respond on lunch break or whatever... I like it when a new offer comes in when I'm online because then I can respond within a few minutes, but not everybody will do that, I understand if they can't respond within 10 hours but 24? Not very professional...
I've found a good majority of Best Offers on eBay these days are automatically rejected due to sellers having very narrow ranges of prices they will accept. Anyway, for the others you should be able to select response times of 12, 24, and 48 hours: Now if you find another item you'd like to buy while you're waiting to hear from the seller, you can initiate a retraction: https://www.ebay.com/offer/retract?guest=1. eBay frowns on this being done in excess but if you do it only when you feel you need to you will be fine. Just select that you put in the wrong amount or didn't hear back from the seller (which would be true in your case for doing it).
I have gotten great results with offers most would consider total low balls to begin with lol! Because you never know how badly they want to sell that coin/item! This might surprise you but I often offer less than half the asking price! I also include a short message saying something like "I don't want to low ball you with my offer but would like to offer you $___ because it's a coin I would really like for my collection but can only afford this much. Thank you so much, I apologize if it comes across as a very low ball or insulting offer." I have had people come back with only asking for a little bit more than I offered. Timing is everything, and also this of course sometimes works for me during the holiday gift giving season when folks are just trying to generate spending cash. Most recently I offered $85 for a slabbed PCGS coin listed for just over $300...seller came back at me with $150, I replied with a new offer of $105...seller then offered $130...I accepted And I of course include a very appreciative note and promised to leave good feedback without mentioning that a low price was accepted...and I did leave nice feedback! There is a lot to be said for tact
