While Amazon Prime Day $AMZN was bigger than ever this year, one key category took a hit in the US. Electronics sales decreased by 5% from last Prime Day, while growth shot past 25% in home, garden, and tools, as well as in beauty and health.

Beyond the chart: The July event coincided with some of the highest inflation rates in decades. Many consumers chose to forgo discretionary items like consumer electronics, and some of the growth in other categories is likely due to higher prices.

But the trends could be different if, as speculated, there is a second Prime Day in Q4. With students back in school and signs that inflation is easing, demand—and funds—for electronics could return.
