My friends don’t really know me, and what they want to get for my birthday isn’t something I like

So, the title gives a bit of context, my friends are not aware of what I like gift wise because I don’t talk about it much , since my birthday is coming up there looking for gifts, let’s call my friends A B and C so B and C told me what they wanted to get me and B said she wanted to get me a MH doll which I would def appreciate but she said she might not be able to get it and her second option is a figurine and my other friend wanted to get me a figure or Yuri and I don’t want any of those things.

It’s fine but I don’t want them to waste their money, and I want to give them some gift ideas but it feels very rude giving a list, what do I do ?
