Can an accepted offer be a lowball offer too?

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

If seller regretting accepting your offer, see if he will take the Item back. It's best to part with the item now then regret later if you are not pleased with your purchase...even at the cost of shipping out of your pocket. 

Why would I return an item if the SELLER has regrets?
