its a giant corporation that looks at prophets and decides the price of the merchandise. so most likely the company is like ok nugget costs 10 cents so we change 12 cents to make a profit but because of theft make it 13 but it could be more then one person next month so we will charge 15 and if no one steels we make extra. ya don't thank this guy he isn't giving you free stuff he is helping you pay more.
This is another thing that sounds good, but actually isn't when you think about it
