well u can use dialogs , its very easy :

here is an example for a /shop dialog :

Code:

public OnPlayerCommandText(playerid, cmdtext[])
{
  if (strcmp("/shop", cmdtext, true, 10) == 0)
	{
	  ShowPlayerDialog(playerid, 1, DIALOG_STYLE_LIST, "Welcome To Shop", "Health\nArmor\nNrg-500", "Accept", "Cancel");
		return 1;
	}
return 0;
}

Code:

if(dialogid == 1 && response)
	{
	  switch(listitem)
	  {
	    case 0://health
	    {
	      if(GetPlayerMoney(playerid) >=1000)
	      {
	        GivePlayerMoney(playerid,-1000);
		      SetPlayerHealth(playerid,100.0);
		      SendClientMessage(playerid,LIGHTGREEN,"=Shop= Thank you For Purchasing!");
	      }
	      else
	      {
	        SendClientMessage(playerid,LIGHTGREEN,"=Shop= You Do Not Have Enough Money For That Item");
	      }
	    }
	    case 1://armor
	    {
       	if(GetPlayerMoney(playerid) >=1000)
	      {
	        GivePlayerMoney(playerid,-1000);
		      SetPlayerArmour(playerid,100.0);
		      SendClientMessage(playerid,LIGHTGREEN,"=Shop= Thank you For Purchasing!");
	      }
	      else
	      {
	        SendClientMessage(playerid,LIGHTGREEN,"=Shop= You Do Not Have Enough Money For That Item");
	      }
	    }
	    case 2://nrg
	    {
       	if(GetPlayerMoney(playerid) >=2000)
	      {
	        GivePlayerMoney(playerid,-1000);
		      SpawnVehicle(playerid, 522);
		      SendClientMessage(playerid,LIGHTGREEN,"=Shop= Thank you For Purchasing!");
	      }
	      else
	      {
	        SendClientMessage(playerid,LIGHTGREEN,"=Shop= You Do Not Have Enough Money For That Item");
	      }
	    }
	  }
	}
	return 1;
