Pros
You are free to instruct your lessons your own way. You can also communicate directly to your students and their families to work out schedules and makeups on your own. It's awesome that you don't have to deal with the payments from people. They are put on auto pay and that's that, you get your money. I liked having access to all the books in the store to view new material, and, or, sell to a student for use in lessons.
Cons
They take 1/3 of your pay!!! Such robbery! Most teachers in the new pay system use the store to build a client base and then walk away with the majority of their students so they can earn all they make. Also, the stores have gotten very corporate. They will attempt to schedule students 6 hours straight, back to back, without allowing you a 30 minute break to eat or anything else. I was told "well we assume most days someone will cancel a lesson, and you can take a break then". Awful. Aside from those grips though, it's still a good place to start out.
