Having previously made a $60 donation, we thought that adding another $40 donation would get us junior moderator. But we realized we goofed because we put the wrong thing in our "cart". We selected a $100 donation option, and it charged us $40. So we were thinking we would write off the extra $40 donation since we found the "junior moderator" designation, but when we put it in our cart it reflected the full price of $100 while we expected it would only charge us the $40 donation difference. Are we doing something wrong? Did we ruin our chance to have the original $60 donation count toward the junior moderator fee when we made the second donation? Thank you in advance for any advice!
