Thank you for considering to back the project! I am so grateful! The reason it switches like this is because for the $100 reward you also get a hat or t-shirt! If you click on the "No Reward" link when donating, then the full amount will go towards donating a 4th gown! I hope that helps! There will also be survey going around where you can opt out for the reward and give the gown! So there are two ways to make sure that for $100, you are giving children with gowns!
