Notas sobre los Rappels y los descuentos uniformes

We consider commercial discounts for buying based on rappels. If a uniform type discount is taken, then an unwanted paradox appears: the “buyer trick”. To avoid this paradox, two proposals are presented. Both of them observe the basic principle “to a greater order, a greater discount”. The first one is that of continuous discounts. The second consists of following a table of graded discounts.
