I'm planning to sign up soon and get the $275 membership. But, i read all the reviews on yelp and many said they got charged additional and hidden fees. Do you have to pay with a credit card or can you pay with cash? My dad most likely wont let me sign up if it's credit card and he'll go apeshit on me if he gets charged extra and never trust me again. I just want to learn MMA and not go through all this trouble.Also do you have to pay $100 for a t-shirt and gears?
