Yes, living 'Online' is always an 'adventure'. I used to be able to drive 1/2 hour round trip but was limited to just 1lb (each grade) per person per visit. But alas, even if I was still in that wretched state I doubt that is even so any more...I have never had to order powder on line and after hearing your experience I am thankful. Two hour round trip to pick it up but I always try and get enough to make it worth the drive.
I was shocked to find that NO ONE in Nevada sells it local!? And it's a good 6+ hour drive to Idaho or a 7+ drive to Arizona....so Online it is, buy enough so you dont have to do it again for a while.
My wife has been waiting 2 weeks now for a toilet seat she ordered....
