Having an annual check day is a really good idea. Mine tends to be every November during Open Enrollment for our insurance. They usually do a vendor day where the different companies come in to let us know what changes are coming (and convince us to choose their plans, of course). They always being swag like the pocket first aid kits, branded bandaid holders, etc. I usually talk to a few of my co-workers and get the stuff they don't want. Great to keep in handy places then keep a few bigger IFAKs/FFAKs in strategic spots. I normally take that time to check mine and rotate stuff.
