It happens. You may not feel good about it but it happens and what can you do about it? It too happened to me but I just blacklist the seller in my phone and move on. I never bargain so it is not like I ask for the seller to sell lower but yet the seller can still find someone who will buy higher and worse still, all the excuses are the same even if it is from different people. Sorry, I decided to sell to my cousin or friend. In life, you win some, you lose some. There will be other deals in the future. So just move on...
