Cumulative students coupons

Good evening,

I opened this topic to get information. I would be willing to buy a Dell Inspiron shortly due to the discounts that Dell Italy is doing. I am a student and I have the possibility of using a discount code for purchases on the Dell website. Unfortunately I can't apply the discount code for students after applying the one for spring discounts provided in these days. My suspicion is that the codes are not cumulative, yet I do not understand what would be the advantage of having a 5% discount for students if this cannot be exploited to their full potential. If you decide to buy the product clearly it would be more advantageous to take advantage of the spring discount than for the students and the latter would remain unused. Clearly one could decide to use it for a later purchase but I imagine that the purpose of these coupons is to help students who actually, if they use it, is because they cannot (or if they can with significant difficulties) face excessive costs and therefore do not could afford to face a further purchase. I would like to know, therefore, if there is a way to exploit this student coupon together with the spring discount code of this period.

Thank you for your availability.
