OK, that's no point to argue further by posting screenshots of PMs with comment.

The point I start the topic is to show the evidence that encore did break his own promise in the process of selling his Axim.

So let the evidence speaks for itself and people do the judgement.

My advice to potential seller, please state clearly in your offer:
1. 1st come 1st served

Don't simply give empty promise (like reserving) to any potential buyer if you just want to sell your item to the buyer who gives you the highest offer / best offer.
This is to avoid unnecessary misunderstanding between seller and buyer.
It will save the seller from ruining his own reputation.
