I placed an order too. I'd hazard a guess that their order volume spiked when word got out about the 15% discount. I got an additional 5% discount by using my Discover card. I ordered a bunch of .45, 10mm and 9mm hollow points.
They also have 55gr fmj in stock, but not at the 15% discount. They've been really hard to find, so I ordered several thousand of them, too.
