GNC has a horrible product return policy. I regularly purchased a workout booster product from GNC for several years. Last purchase, the store employee told me there was a promotion and I could buy two and get a third can free. Awesome I thought! When i opened the third can - the product was bad. It had gone hard and couldn't be used without a chipping hammer. But I was bringing it back more than 30 days from the purchase date. REALLY!? What was i supposed to do. - Well no more GNC products for me or any of my friends!
