Some people are worried about long term interaction with the plastic. I don't really know. I have both but typically use glass for long term and plastic for short term.
The MFS sale says they will be shipping in HDPE plastic, no exceptions. Either way, now I won't run out for a very, very, very long time.
Laws be dammed we'll always be able to get VG.
Thanks for the heads up Monkey - that's a pretty insane deal.
(I hope you did cash in on it... for making poo of course)
