The ability to make minimum wage is never ideal, however, commission does make up for it. A typical day involves a lot of product reviewing (as the industry changes constantly) and guiding customers along their purchase as they come into the store.
A good chunk of what you make in commission can be based on if your location is busy or not, however, every slow location can be made decent if you can make a sale.
It is a very sales orientated, target driven company as is any other sales organization.
If you are looking to get into the company, read sales books, job shadow the tops sales reps and emulate them at the beginning until you find your own comfort zone.
Work evenings and weekends if you want to make high commission. Much less foot traffic during the day (for the most part).
They will move good sales reps to better locations if they can prove themselves.
The ability to move up is easy if you are patient enough and can hit your targets consistently. Even manager in each location was once a sales rep.
