I suppose they will demand that all those with supplies donate such to the communal stock, so they can give them out as they see fit (hint: Those that contribute the most will probably not get the most back). It will be those who pious-sneer and do the most for joke-hova that get the most. This is why every individual needs to look out for themselves and family first. Of course, it helps to have a job that pays a decent amount, which is not possible given washtowel rules.
And, to add to the list, BATTERIES! I expect the results of the election to be a big mess--Biden ultimately getting placed in. The patriots will try fighting back, only to be vanquished and full communism imposed. This will be quite messy, and I am expecting frequent and long-lasting blackouts to happen as a result of this war. (Worse than a storm--at least with a storm, you don't have people shooting back at you while you are trying to restore power and Internet.) Get DVDs or downloaded videos, since you are way more likely to lose your Internet for a long time or for good than electricity. Make sure you have a decent stash of working flashlights--there is no worse time than Jan 10 to find out your flashlights are duds, and all the stores are sold out of them and have limits of one total package of batteries per customer (if you can get them at all).
In addition to batteries, you might wish to get games you don't need Internet to play. Those old Nintendo DS cartridges may give you some entertainment if you have electricity but no Internet or you can secure a good stash of batteries for them. Board games and cards are also nice, as are good books. (I mean paper books, not digital books that require Internet access to read, let alone electricity). If your walls are boring paint, some nice posters of your favorite theme will be nice if you order them before Jan 9 (again, the worst time to try is after the lights go out and there is no Internet). And, candles throw off quite a bit of heat along with light, but can be messy and start fires if you are not careful and don't know what you are doing with them.
If you do that, you will not be relying on any congregation of jokehovian witlesses when the power and/or Internet go off and stay off. Do not give any of your stash to the congregation, since everyone should be looking out for themselves and families, not the whole congregation.
