Your last post "confirming" you want to buy is on 26th Sep, while my post was on 23rd Sep.

There are 3 days you did not show commitment and why I should wait for your reply, while lots of others show theirs.

I count the person saying "OK I will buy this for this price" as the deal, and if I changed mind (mostly I won't) or selling to other I WILL DEFINITELY let him know in the first place.

For the person just showing interests, sorry.

Perhaps next time you would mention your intentions or confirmations earlier.

And again, sorry for your inconvenience.
