What does a PLU code look like?
You won't find PLU's at the farmers market they are used by grocery stores to help price your produce.
If the code is four numbers in length and starts with a 3,4 or 5 it is "conventional" produce
If the code is five numbers in length and starts with a 9 it is "organic" produce
If the code is five numbers in length and starts with an 8 it is genetically engineered produce
