Imagina que estamos implementando una tienda online, que vende solo 3 productos:

Codigo | Nombre | Precio
_______________________________

AM | Agua mineral | 3.11€
AC | Aceite | 5.00€
CA | Cafe | 11.23€

El departamento de marketing es fan de las promociones de tipo 2x1 (si compras dos productos iguales, uno de ellos es gratis). Y quiere que haya un descuento de este tipo en Agua mineral.
