What do I save? (Posted on 2006-08-11)

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?

When you finish the free box, you must only buy four more, and you will get the free one, so savings are 20%.
And, in reality, it isn't exactly 20%, because the first time you HAD to buy five to get six; it's only from that point onwards that you get five for four.
