Math help

[Strangler Lewis]

I'm no expert, and I've certainly bought my share of jams from the nice ladies at the farmer's market who claim to cook in their kitchen and whose jars are not necessarily sealed. However, if you are truly trying to market something, I wonder if regulations might not require you to be a bit more exacting in your labeling, packaging etc.

Maybe you're already on top of it. Maybe Gn2Dlnd has insights. At any rate, good luck with it.
