@In-x-s I purchased those Durkee FF onions today as well! The funny thing is mine were $1.89.
Eggs at my store are .45 cents. 15 minutes away at another Aldi's, they are $1.89. I have NO IDEA how Aldi does its pricing but obviously it's not a set price; not even at stores just a few miles away from each other. Knowing this, the only way (IMO) you can keep track of whether costs or rising or not is by keeping tabs on store you always frequent.
My thoughts on Aldi increasing prices is this: if Aldi's is this expensive (on whatever you're purchasing), then how much is the big name store charging for the same thing? ANd how are people affording it?
Another example: I purchase the Aldi's brand of Jalapeno potatoe chips for school lunches. One bag is $1.29. This is an exact copy (down to the graphics) of Lay's Jalapeno potato chips which cost $3.99 at Walmart and is $4.29 at my local Giant for the same weight. Big price difference and why I now shop at Aldi's; I have many mouths to feed and my dollar goes farther but...for how long. That case of soda may only be pennies for a can but for those who buy this as a treat and can't afford the gas station or Starbucks (what a joke), that increase means that one treat is now gone as well.
I budget down to the penny. I was taught to make my money work for me as hard as I work for it. But in the end, you only have so much in the bucket that you can spend. As the cost of food rises (and it is) the choices become more and more difficult regarding what you're going to be able to purchase. For many, that's no big deal. For far more, it is a big deal.
