Get a FREE Apple iPhone screen protector. Credit card number is required. Make sure your total is FREE or $0 before you submit the order. But it seems to go through with prepaid credit cards with little to no balance if you have one. They shipped the free USB cable they offered back in March so it’s legit, but I would stick with a prepaid card since the site is fairly new.
