Just browsing the Costco website. It seems they've really added to the preparedness section. Lots of long term food storage options, as well as some gadgets.

They are also stocking some of the forward osmosis water filters that folks have talked about.

Anyhow, no affiliation, but a satisfied customer. I've never tried any of the products I'm pointing out.
