Query: Price. Yikes!

This item is a single tube containing 2 eraser refills.A single tube. The price of this single tube is $1.09 at Office Depot. I know, right?The photo dazzled me, and the product shows a list price of $16.08. $16.08 surely would be the price of a full box. I've used these erasers in the past, so I didn't read the "Product Features". My greedy self clicked the "buy" button without further question.At the time of my purchase, the price I paid was $4.00.
