Kauf
B1Kauf refers to the singular act of purchasing something or a particular purchase. It usually describes a specific transaction or the process of buying one thing. It has a more focused and narrower usage than Einkauf.

(The purchase of this book was a good decision.)
War der Kauf des Autos teuer?
(Was the purchase of the car expensive?)

Summary
Einkauf generally refers to the process or collective act of shopping, often involving multiple items or goods, while Kauf refers to a single, specific purchase or transaction. Use Einkauf when discussing shopping as a general activity or multiple items, and Kauf when focusing on a particular purchase.
