TweetGNC is the king of sleazy upselling. You cant buy anything there without the salesman trying to talk you in to buying a discount card. Discount cards are stupid. Paying money to save money is a con job. I . I bought a discount card one time just to shut the person up, then when I went back, they tried to upsell me to a premium card or some kind of crap. Huh??? I hate GNC
