You're right, but I was thinking of the buckets that are basically terrible quality slop that's borderline inedible.

I might still call it a grift because they're asking for payment as "donations" to skirt paying taxes on them. That, and like you said, it's not a great value for what you get. Maybe not pure snake oil, but there's definitely still enough dishonesty involved imo that I'd be comfortable calling it a grift.
