I am also thinking of buying a 50lb bag of lye. I don't want a million little containers of lye sitting around though. My husbands suggestion was for us to get one of those big Space Saver Bags. He said, "Well, they say it keeps out air, moisture etc!" Hmmm......I think I just might do it. The price difference is simply AMAZING!!!!! $57 for the 50lb bag and no shipping because its local. I do have a couple of the 2lb lye containers left though. I have a funnel that I can designate for refilling the smaller container from the bag, then reseal.
