Each retailer is different since they are independently owned. However, when I worked at a 100% commission store there was no health insurance and no training, they just went over the basic components of AT&Ts plans and advantages but they didn't "teach" you how to sell you were expected to know. Also the commission wasn't split evenly between the reps it was each and every rep for themselves. Which when you think about it is better you don't want to work your butt off just to make a decent check to pick up the slack for lazy reps. Good Luck
