Shops

General info

You can purchase things directly if you spend less than 100€ including taxes (obviously with authorization of your tutor). Give the receipt or invoice to your tutor to obtain refund!
If you need to spend more you need to refer to your tutor to start a different procedure.

RS - You can shop on-line or buy direct from the RS shop located in via W. Tobagi, 19 - Vimodrone (near the "Cascina Burrona" stop of MM2). Important! If you buy directly at the RS shop, you absolutely must request that the name on the invoice ("fattura") is: Politecnico di Milano - Dipartimento di Elettronica e Informazione - via Ponzio 34/5 - 20133 Milano", and that the invoice is marked as paid (RS uses a strange paper-piercing tool to do this). If you ask for these two things, you get a 10% discount; if you don't, you don't get the discount and, above all, you cannot obtain a refund from your tutor!
