E-commerce is growing steadily.
This chart from the US Census Bureau doesn't include food or travel. If the charts were broken down by city vs suburban vs rural, my suspicion is that our rural area would be above the average % of e-commerce. However, big-ticket items, like a car, can skew the charts. For my normal purchase habits, gasoline, food, greeting cards, some hardware and most clothing is bought locally. The rest is Amazon prime.
For a junk food craving after Heath's is closed, Dollar General is an interesting option. After my first roam through the aisles, I left without buying a thing.
