Absolutely the third option listed, one million rounds.
If my neighbor has one million rounds, I'm definitely nervous that he's gotten one helluva buy from somewhere, or gotten a smoking deal on powder, primers and slugs, both of which I have missed.
Hell, when my best shooting bro buys a case of rimfire, I get really nervous, because I know that if he's buying, it's a sale good enough where I'm a fool if I don't also buy. (for the record... he grabbed two cases of CCI-SV a month ago and I went ahead and picked up one case. And the time before that, we each bought up to our limit in one shipping fee and that was 8,000 rounds each.)
