Enough people have sent me this now (including leaving it in comments on other posts) that I feel like I have to feature it.
You can get free samples from Walmart. They change periodically.
I am not a Walmart fan, so I am in no way endorsing this particular freebie. But free is free, regardless of the oppression of the masses, apparently. Or, hey—maybe if enough of us go for the free samples, they’ll go out of business! (Oops. Did I say that in my out-loud voice, again?)
