:) At Whole Foods, they had a misspelled tag one time that said "Arrugala", and another a different time that said "Greeen grapes", and I am not kidding XD!! Nobody checks things anymore.
I love mislabelings! This reminds me of a clearance sign I saw in Walmart. It was big and said "Was $6.47, Now $47.88" XD I still have a picture of it on my phone!
Hmm... maybe the corn was the same price as the watermelon because of the sale so it didn't matter what code they punched in to print up the labels but then they ran out of ink for printing the word corn
