Because of cholesterol problems, I must take a certain medicine. Every week I buy a box, which lasts me for seven days.

However, things are not so bad. The laboratory that produces this medicine has an standing offer: for every five empty boxes, they give you a free new box.

Thus, I get six boxes paying just for five; it means a 16.67% savings for me... right or wrong?

Thats assuming a few things like that there is a week's worth of dosage in the "new box".
