Slow to respond, but a core part of microeconomic inflation. are fuel costs. Here, back under $2.50/gallon for 87 octane regular gas, now. That's down from a high of $4.20/gallon a couple of years ago.
Diesel is similar, and perhaps more relevant (although most of us drive gasoline vehicles) because it is diesel that moves cargo, and the transportation costs made for a surcharge on the consumer or loss of profit by those depending on motor transport of raw materials, subassemblies, etc. (before shipping final products to consumers).
I am painfully aware of how far those prices have dropped, looking at a 90% reduction in my non Social Security income as the drilling industry here implodes slowly. Thankfully, I can survive fine without that income, just a little tighter belt, not crisis, because that was mainly my source for discretionary funds, not essentials.
