This might seem fairly obvious to everyone else, but I was kind of surprised by it, so I'll share it for all the people that are as challenged as I am.
I was trying to find an alternate source for granular lecithin because I didn't want to pay shipping costs from King Arthur Flour . . .
Anyway, people use it as a nutritional supplement so you can buy it from vitamin and health food stores. I got some at Whole Foods today. It was cheaper than KA and it comes in a canister which is nicer is my pantry than the bag was.
I'm so pleased.
