Buyers pay. Sellers receive payment.
You can also remember:
- The customer buys.
- The shopkeeper sells.
- The buyer receives.
- The seller gives.
This simple contrast makes the difference easy to understand.
Buy and Sell in a Shopping Situation
Imagine that you visit a clothing store.

The shop assistant gives you the shirt and receives your payment. The shop sells the shirt.
Here are both viewpoints:
- I bought a shirt from the store.
- The store sold me a shirt.
- The customer bought the product.
- The shopkeeper sold the product.
Both sentences can describe the same event:

The difference is not about the product. It is about who is giving money and who is receiving it.
