My Costco keeps running out. I'm 50 / 50 this year when I go in. It is still very cheap, which is great, it is fairly crucial for my life and other options are much more expensive. I feel like a conspiracy theorist even saying this but I think getting the bulk packages at cheap prices from Costco may be going by the way side. ¯\_(ツ)_/¯ I've literally got friends picking it up for me whenever they go.
