Couple of things to think about here..
1, 30TH Was thursday, even if sent out on friday unless he paid extra to have it to you on saturday of which i doubt he would for such a silly amount of cash it wouldn't get to you until mon/tuesday if posted first class..
2, Is it possible if he hasn't logged on that he might be in paris playing , if so he certainly isn't posting anything to you from there..
3, As everybody has stated not everyone has the ability to sell and send it out the next day..
Be patient and as said if he comes online and then still fails to respond to your pm's etc, then think about what actions to take..
