we all know the Iceblade/shatter rounds scam, but now, Blizzard made a much easier way for us to apply it without resorting to addons/macros/whatever
First, buy a stack of 1000 arrows/rounds, it will be around 5-10g depending on your server
then, with that stack, go to the auction house and put it up on the auction slot, and select 1000 stacks of 1 (or whatever number of arrows/rounds do you have, in the case of our example, 900):
after that, on the dropdown menu below, select "per item", and add a low value to the bid (like in the example, 5s) so the auction appear first on the list, and undercut the 1000 stacks by 1g, 2g (in this example, 1,5g because the stack was 3g at the moment of selling) and the duration to 48h
after that, just click create auction and wait the magic happen
depending on the amount of demand of the huntards on your server, your mailbox will be flooded with 1,50g auctions, so grab an addon like BetterInbox to open them all
doing this at raid nights gives better results, and prepare to also receive complains, so do this on your bankalt or a char that you don't log in much, and prepare do fill his ignore list of huntards
good luck!
