Please inform me to the location of cheap oats, 2€ a kilo isn't right now.
For example, cherry-picking Quaker Foods North America, PepsiCo 23Q1 earnings reported[1] +10% revenue on -5% volume; this pattern is rearing its head across the consumer staples sector.
Putting this into pragmatic perspective, local prices where I'm at are $5.68/42oz ~= €4.30/kg for Quaker Oats name brand as a proxy baseline, while Walmart's Great Value house brand are $3.98/42oz ~= €3.00/kg on the cheaper end of the spectrum.
