I signed for the website www.yipit.com, but I really wanted to advise all people to stay away from them. I provided them my personal info and card number, ‘coz it was necessary in the registration. After that I searched for the coupon, but all coupons suddenly were unavailable. I was surprised, but the situation repeated again and again. Please, be careful and better don’t deal with these jerks. Total rip off.
