Can an accepted offer be a lowball offer too?

If a seller actually accepts an offer with no conditions attached (a fine but important distinction), but then starts complaining later about accepting that offer as somehow being too low $$-wise in hindsight (... ergo, misguided seller's regret about his own doing.... ) then seller is a moron with nothing to complain about, full stop.

ditto selllers regret does not interest me .we could fill a gig of space listing the things we all wish we hadn't or sold too cheap. I want my tandberg reel to reel back damit.oh that was 25 yrs ago lol

I feel the same way but this has happened to me. I made an offer on something, paid promptly, and received the item which as not in the excellent condition as advertised. I mentioned that and then the "lowball" word came out. As far as I kniw I did not force the seller to accept my offer! Seller's regret no doubt. 

Gosh knows i have been disapointed when i opened up a box and saw what i paid top dollar for .Happens all the time from ebay ..luck of the draw ,thats why trusted sites are best.But if i accept an offer ,how is that being low balled i am not pawning if lol

Yeah well, I didn't understand it either
