Sales Outlet - using Tkinter for GUI
Punto de Venta - usando TKinter para la Interfaz Gráfica

Abraham Magaña Hernández & Gerardo Gabriel Mercado Guerra

This is the first time i've been working with GUI and i really wanted to use a database but i don't have too much time to learn that
im pretty new to this and i make this work using only code and large lists.

La primera vez que trabajo usando interfaces gráficas, realmente queria utilizar una base de datos para este programa, tal vez lo haga
en un futuro, pero por ahora funciona usando listas de los productos.
