The plural of anecdote is not data. My spending has remained more or less constant.
The supply chain in soda is complex, you have corn producers (whose equipment, fuel, labor, and seed costs are influenced by supply), the price for corn is increased as global farm production is hit by war, you have water costs (which, depending on region, could be increasing), you have fuel and distribution costs, labor costs, plastic bottle costs... I guarantee you can trace back increased costs to regions hit hard by pandemics.
I think you're alone if your spending has remained constant. I don't know of a single grocery item that I buy that hasn't gone up in price significantly.
My wife used to work for a well known food brand. Somewhat early on in the pandemic grocery stores raised their prices for that brand's products, even though they weren't paying any more for the product. Eventually the brand did raise their own prices as they decided they'd rather have that money themselves.
In both cases it was as simple as other prices being raised, consumers had the money to spend, so why not?
