Just an FYI -
Ordered some QF 5.7 from an online retailer through Amazon yesterday at 3pm or so and it was on my door step when I got home today at 1pm. Did overnight shipping for 2 bottles and only paid $53 total for all.

Batch #F5G-09 on the box I opened to check. Both were sealed so I assume they are good to go.

I'll report back if I have to use it.
