I read it as "For items in the ten to twenty dollar range, its not worth adding a vendor label" and I don't suppose its the cost of the sticker, but how much longer does it take the warehouse worker to take it from a shelf and put it in a box if they add a sticker to every item? +5% ? +10% ? +100% ? (It takes very little time to put an item in a box, I could see adding a sticker doubling this...)
