Saw this on Kottke.org. Looks like several of these are the Kirkland brand that you get at Costco. Roughly the same price but with out the membership fee.
If you’re like most people, you purchase Benadryl. A slightly smaller and savvier subset of you will always reach for the drugstore’s “generic” counterpart, e.g. Waldryl. Stop this madness, all of you.As you might know, Benadryl (available at Walgreens.com for $5.29 for a box of 24 capsules) and Wal-dryl ($3.99 / 24 capsules) are otherwise known as “25 mg. of diphenhydramine HCI.” Compare. Yes, that is 400 tablets containing 25 mg. of diphenhydramine HCI, for about $10 when you factor in shipping.
