Hello there!
Staple and Impulse goods tend to be around places like the supermarket/stores/etc. Here are what they are:
Staple goods:
Goods that consumers buy on a regular basis, and consumed regularly.
Staple goods are very common in places like supermarkets. Staple goods are goods like milk, eggs, bread, sugar, etc. These items are what consumers usually go to the store for, and they usually put these specific items on their "to buy" list when they go shopping.
Impulse goods:
Goods that tend to not need planning in order for a consumer to buy. This is typically known as the "surprise lets buy that" type of goods.
Impulse goods are goods that people usually don't think of getting, but when they see it, they get it anyways. These would be known as things like snacks, candy, etc. People usually don't put those items on their "to buy" list, but when they see it, they buy it anyways. To sum it all up, these types of items do not need planning to buy, and could be an "out of nowhere" purchase.
