Everybody has been doing it for a couple of years, and it is going to get worse.
I'm sure you're right about that.
I hadn't noticed the raisin switch before just the other day, but the guy who made the youtube clip apparently discovered it months ago.
(I like the way he showed the old and new packages together, as well as his two Walmart receipts, and how he pointed out that an adult can't even get their finger into the new smaller kind of raisin boxes. I thought he documented the problem pretty well, at least for raisins.)
