Also the price of ground beef (for the cheapest ground beef, at the cheapest grocery) just went up from 3.75/pound USD for the 20% fat (which is the most common) - to 3.99. So that's a 6.6% increase. Hope it goes down again.

Also maybe next time you do this, ask for the price of eggs. That's gone up a lot here recently, it's currently 30 cents for one egg. (That's the cheapest kind, but I just checked now, and there's another brand that is selling for 28 cents an egg. Need to switch!)
