Pros
You have the potential to make high per hour income. This based on sales ability and knowing how to build stacks with the right products to make the most commission possible. This can range from $0-200 extra a day plus your minimum wage hourly pay. Not bad for part time.
Cons
Now the bad GNC is run on goals of achieving certain percentages in different categories in the store that if not met could lead to termination. Gold cards have to be at 18% so about 3-4 a day, foundation (protein, fish oil, probiotics) 24% a day, P3 certain gnc products and 3rd party products 38% Multivitamins 16% all divided by your total sales for the day. Now here is the kicker if you get a return on any product within these categories they take it off your percentage not the person who sold even if its a different store. Recently I should have had 20% in multi's and 40% P3 but because of two returns on something I didnt sell I ended with -11% multi and 18% P3. This is unfair and destroys morale when it happens.
