BO has to be up 1 week for every 25 keys. Can you read over the rules/guide before you do a bunch of these? Also if there are sales (which there definitely are for some of these hats) then sales would be much better to use.

Ghost safeguard is unpriced. Judging by its current OP buyouts, this sale would conflict with the current sellers

Sales generally between 25 and 32. Incidentally, the suggested value is close, but a range would be better.
