Ran across this online retailer that specializes in those teeny little packets of a variety of products (including some FAK stuff):

Thought a few people might be interested. Don't know about the prices, but at the grocery store the other day I noticed that the price of a pack of 2 caplets of Tylenol, Advil, Benadryl, whatever, was a buck. Ouch.
