My wife sent me to CVS to buy something I'd never heard of. You can guess what happened. I looked at a long isle full of similar products, and I just couldn't find it. I finally begged a CVS employee for mercy, and she found it for me in no time.
Next time I have to find an unfamiliar product, I'll do better. This IS the 21st century after all. I'll examine the product on the web before I shop, so I'll know what it looks like.
