Etymology of お負け


In my flashcard studying of JLPT1 vocabulary I've across お負け with three
English definitions (from JMdict):

  1. _freebie_ ,
  2. _price reduction_ ,
  3. _exaggeration_.

Now my question is how adding an honorific prefix to 負け ( _loss_ , _defeat_ )
has come to mean something positive (well, at least for the receiver). Is it
because someone concedes something to someone else? E.g. a salesperson
conceding a customer a reduction in price.

And what about the third definition, _exaggeration_ , which seems unrelated
the first two? As JMdict does not provide a sample sentence for this
definition I'd be grateful if someone could provide one.

よろしくお願いします。

N.B. I am unfamiliar with the tags of the site, so moderators are free to add
additional ones.




Leo's guess is actually right. For reference, it is enough to go on the
wikipedia page of
[お負け](https://ja.wikipedia.org/wiki/%E3%81%8A%E3%81%BE%E3%81%91).

The meaning originally comes indeed from the fact that the seller is losing
something in the bargaining process (from wiki):

> おまけの語源は「御負け」の文字通り、店員が客との駆け引きに負けて値を下げる行為を指す言葉であったが、のちに商品以外の物品を追加する行為なども言うようになった.
