Transactional database

Hello everyone: 

I am Professor of Data Mining. Right now I'm preparing some cases for the next semester and I was wondering if any of you have a database that you can share with me. The database should contain transactions made by customers, including date of purchase and what it takes. It would also be ideal if you had another database containing customer information, such as date of birth, marital status, number of children at home, to name a few. The idea is that students can use this database in different projects, first to do aggregations (which is why I ask individual transactions), then do clustering of customers and later models propensity to purchase and market basket analysis. I already have a very good database, but just used this semester, if someone wants to trade with me or want to ask me to play with KNIME or because it is also a teacher, I have no problem with sharing. 
If you're interested, let me know. 
Thank you very much.
