I'm not saying the value is like churning an Ink Bold card, but it saves money, and shouldn't take long to do (especially with autofill) - so why not? I'm not telling you what to do, but it's not that crazy. Your prices are a bit skewed, though.
wipes - more than 5 cents, probably .20 a package, if you value them at the same price as a full size pack - but it's also the convenience, being able to stuff them in a diaper bag to go.
Shampoo - I shower 3-4 times a week. Depending on the type of shampoo, each packet can last several showers. I've gotten dozens of these.
Toothpaste - really? Where do you get toothpaste for $.10? Having about 10-15 samples size is at least a few full size tubes.
dental floss - it's a tiny amount, so less than .50, but again, it's convenient to have an individually wrapped piece.
tide pods - .10? Where are you getting these prices from?
