Example data source for educaional use I'm doing project on subject of affinity analysis for my statistical class in college. 

In order to complete it, I have to acquire sales database with at least 200-300 records, each containing list of products bought by single client.

Are there any example sales databases available for free to use for such educational purposes?
The description of the needed data is quite general, but I have found this dataset that describes sales during Black Friday; it is possible to identify products bought by the same customer using customer_id column. 

Also, this dataset describes transactions from a bakery. The products that were bought in the same transaction (and so by the same customer) are identifiable as they share the same #Transaction value.

Generally below are 2 sources where someone can find free datasets that can be used for training/ educational purposes:


Kaggle: https://www.kaggle.com/datasets (both datasets that I suggested were found here)
EU Open Data Portal: https://data.europa.eu/euodp/en/data
