Jay, I don't pay a great deal of attention to online flour prices because of the shipping prices involved. I'm also a little wary about the turnover for these products and their freshness. At times, it's been very difficult, but I have yet to find someone that couldn't find commercial flour locally at a better price point, so that's generally what I push people towards.
That being said, occident is a great flour (a tiny bit lower in protein than I prefer, but still far better than 14% flours), and if you've got $30 to spend, this would allow you to experience something spectacular- assuming of course, your oven setup is in order.
Hopefully another member who buys flour online can chime in on the competitiveness of the price, but, other than that, you could do worse. It's definitely better flour than the All Trumps at Pennmac.
