The first person to offer the ASKING price MAY get the goods even if there are offers already tabled but not accepted, (it remains the sellers right to decide what offer to take)
I think the point Lump is trying to get across is that regardless of the amount of previous offers and interest in an item thats for sale, if someone offers the full asking price the seller has the right to ignore all previous offers posted and sell to the buyer offering the full price.
For example, say you have a hopper for sale for £40 and you get the following posts in your thread on the first day its up....
Buyer B: offering £35, will have it 100%.
Then 2 days later you get this...
Buyer C: Will give you full asking price of £40.
As a seller you are in your right to ignore the first two posts and sell to Buyer C without A or B moaning that they showed interest first and should have got it.
This is why the new rule will help sellers from the countless lowball offers that people regularly insult them with, as if they had offered to pay what you were asking for they would have secured the buy.
Of course this is down to the seller if he chooses to sell to Buyer C, he has every right to decide who he sells to.
It will just mean people are less likely to lowball as they risk missing out on the item as soon as someone offers the asking price.
