Overspending on Christmas (long, sorry)

We have an open realationship with our adopted daughters grandmother and birthmother. There is no legal contract for open adoption, but we have chosen to keep them as part of our daughter's life. we adopted her a year ago at the age of ten. Her birthmom has had problems with drug addiction for 15 years, but has remained clean for the last two years, the first one of those being spent in prison. Prior to Christmas I sent emails to both b grandma and b mom asking that they keep any gifts small as 1) we are trying to keep the focus on the love rather than the material side of Christmas and 2) T is one of four children (only one bio) and the only one that would be receiving any gifts from birth family members. Although we realize things will never be absolutely fair or equal, but we don't want things totally off balance. I heard back from both of them saying that they would honor my wishes. B mom said she was going to give her an itunes card and a cd, and b g'ma said she was going to give her "a little money" so she could choose her own gift. Today b mom came over and brought the gifts from her and b g'ma. B mom gave her a double CD, a $50 itunes card and $25 cash! B g'ma gave her $50 cash! How is that keeping things small? I sat there in utter shock! Now, my question to all of you is, do I call or email them and tell them how I feel about their small gifts? Or do I just let it go? I do know that next summer, prior to her birthday I will give them a definate limit on how much they will be allowed to spend. I am thinking $20 is a much more appropriate amount. It is not like she lacks for anything. We have a large extended family. My in-laws have always been very generous in giving to the kids, plus she got gifts from 5 sets of aunt/uncles. Not to mention what she got from us. I am really struggling with this and just do not know if I should say anything now, or just wait till birthday time.
