To determine the median expenditure from the provided information:

- There are 100 customers in total.
- 33 of them spent less than €100.
- 67 of them spent between €100 and €300.

### Step 1: Understanding the Median
The median is the middle value when the data is arranged in ascending order. Since there are 100 customers, the median will be the expenditure of the 50th and 51st customers when arranged by their spending.

### Step 2: Positioning of the Median
- The first 33 customers spent less than €100, so the 34th to 100th customers spent between €100 and €300.
- The 50th and 51st customers are within this range, as they both fall in the group that spent between €100 and €300.

### Step 3: Answer
Since both the 50th and 51st customers spent between €100 and €300, the median expenditure must be within this range. The best option is **€200**, which lies in the middle of this range.

Thus, the median expenditure is **€200**.
